I Used to Run Marathons. Now I Can't Walk to My Mailbox Without Stabbing Pain in My Heels. A Sports Medicine Doctor Finally Told Me Why Nothing Works.

They forced me into useless injections and physical therapy, denying me actual treatment for 3 years just to save money. Here is the 90-second biological breakthrough that finally healed my feet—without a copay, without a deductible, and without asking for their permission.

An Investigation by Michael Reynolds, Medical Correspondent
American Health Watch | January 2026

Mark Sullivan laced up his running shoes.

53 years old. Had run 14 marathons in his life. Boston twice. New York once. Chicago three times.

Running wasn't just exercise for Mark. It was who he was.

But this morning, standing in his garage, trying to get ready for what used to be an easy 5-mile run, he couldn't even make it to the end of his driveway.

The moment his heel touched the pavement, stabbing pain shot through his foot like someone had driven a nail through it.

He tried to push through. Took three steps. Had to stop.

Limped back inside.

Sat on his couch. Unlaced the shoes. And realized something that broke him:

He wasn't a runner anymore. He was just a guy with broken feet.

That was 18 months ago.

Since then, Mark has spent over $8,000 trying to fix his feet.

Cortisone injections. Custom orthotics. Physical therapy. Shockwave therapy. Night splints. Expensive running shoes. Every treatment the sports medicine industry told him would work.

Nothing worked. Not long-term.

And sitting on that couch, shoes unlaced, Mark started to wonder:

Why does nothing actually fix this?

I'm Michael Reynolds. I've investigated the American healthcare system for 12 years.

And what I'm about to tell you is going to make the $47 billion pain management industry very angry.

Because a sports medicine doctor named Dr. Alex Marsten finally told the truth about why Mark's treatments kept failing.

And it's not because Mark's feet are "too damaged to heal."

It's because the industry profits from keeping you on the treatment treadmill.

A patient cured is a customer lost.

THE DAY MARK'S FEET GAVE OUT

Mark's foot pain started in March 2023.

He'd just turned 52. Training for his 15th marathon. Running 40-50 miles per week.

One morning during a long run, he felt a sharp pain in his right heel. Like stepping on a rock. He slowed down. Walked it off. Finished the run.

The next morning, he couldn't walk.

His heel felt like someone was stabbing it with an ice pick. Every step. Especially the first steps out of bed.

Mark went to a sports medicine clinic. The doctor diagnosed plantar fasciitis.

"It's inflammation of the tissue on the bottom of your foot," the doctor said. "Very common in runners. We'll get you back on the road."

The doctor recommended:

Rest for 2 weeks
Ice and stretching
Over-the-counter arch supports

Mark followed the protocol. Two weeks later, he tried to run. Made it half a mile before the stabbing pain came back.

He went back to the clinic.

THE TREATMENT TREADMILL BEGINS

Over the next 18 months, Mark tried everything the sports medicine industry recommended:

April 2023: Custom orthotics. $450. Helped for three weeks. Then the pain came back.

June 2023: Physical therapy. 12 sessions. $840 after insurance. Stretches and exercises. Felt better during therapy. Pain returned two days after stopping.

August 2023: Cortisone injection. $280. Worked for six weeks. Then the stabbing pain came back worse than before.

October 2023: Night splint to keep foot stretched while sleeping. $89. Uncomfortable. Stopped using it after two weeks. Didn't help anyway.

December 2023: Shockwave therapy. $1,200 for three sessions. "Breaks up scar tissue." Hurt like hell. Didn't work.

February 2024: Second cortisone injection. Worked for four weeks this time. Then stopped working.

April 2024: New custom orthotics. "More advanced design." $520. Same result as the first pair. Helped temporarily. Then didn't.

June 2024: Third cortisone injection. Worked for two weeks. Doctor said he couldn't give Mark any more. "Too much cortisone damages tissue."

Total spent: $8,347.

Result: Mark still couldn't run. Could barely walk. Had gained 32 pounds. Fell into depression.

And every treatment followed the same pattern:

Work temporarily. Stop working. Get recommended the next treatment. Repeat.

THE BREAKING POINT

By August 2024, Mark had given up on running.

He'd gained 32 pounds. Stopped going to the gym. Stopped seeing friends from his running club. Fell into what his wife called "the dark place."

"I didn't know who I was anymore," Mark told me when I interviewed him in December.

"Running was my identity. Without it, I felt old. Broken. Useless."

"I couldn't play with my kids. Couldn't stand at my daughter's soccer games without my feet screaming. Couldn't walk through the grocery store without limping."

"I felt like my body had betrayed me. I was 53 but felt 73."

One night in September, Mark was sitting on his couch scrolling through his phone. He saw a photo from three years ago. Him crossing the finish line at the Chicago Marathon. Smiling. Strong. Proud.

He barely recognized himself.

That's when his wife sat down next to him.

"You need to find a different answer," she said. "Because what you're doing isn't working."

Mark nodded. She was right.

But he'd tried everything. What was left?

THE 2 AM ARTICLE THAT CHANGED EVERYTHING

Mark couldn't sleep that night. His feet hurt. His mind raced.

At 2:18 AM, he picked up his phone and Googled: "Why does nothing cure plantar fasciitis permanently."

The first result was an article that stopped him cold.

The headline: "A Sports Medicine Doctor Reveals Why the $47 Billion Pain Industry Keeps You on the Treatment Treadmill. And What Actually Works."

Mark clicked.

The article was written by a sports medicine doctor named Dr. Alex Marsten. 19 years in practice. Treated thousands of athletes.

The opening paragraph hit Mark like a punch:

"I'm about to tell you something that will cost pain clinics, orthotic manufacturers, and pharmaceutical companies millions in lost revenue. But I don't care anymore. Because after watching thousands of patients cycle through the same failed treatments for years, I'm done protecting an industry that profits from your suffering."

Mark kept reading.

THE CONFESSION OF AN INSIDER

Dr. Marsten explained the treatment treadmill:

"Here's how the pain industry works. You come in with plantar fasciitis. We give you orthotics. They help temporarily because they offload pressure. But they don't fix the root cause. So the pain comes back."

"Then we send you to physical therapy. You do stretches and exercises. They help temporarily because they reduce inflammation. But again, they don't fix the root cause. Pain comes back."

"Then we give you a cortisone injection. It helps temporarily because it reduces inflammation. But cortisone doesn't heal tissue. It just masks the problem. Pain comes back."

"Then we recommend shockwave therapy. Or PRP injections. Or surgery as a last resort."

"Each treatment costs hundreds or thousands of dollars. Each one works temporarily. None of them fix the actual problem."

"Why? Because the actual problem isn't inflammation. It's oxygen starvation."

Mark read that sentence three times.

Oxygen starvation?

THE GARDEN HOSE NOBODY TOLD HIM ABOUT

Dr. Marsten explained it with an analogy Mark would never forget:

"Imagine the tissue on the bottom of your foot is a garden hose. When you run or walk, micro-tears develop in that tissue. Your body sends blood to heal it. But if the blood vessels are constricted—crushed by tight muscles and inflammation—the oxygen can't get through."

"It's like parking a truck tire on the hose. The water can't flow. The grass starts dying."

"Orthotics don't lift the tire. Physical therapy doesn't lift the tire. Cortisone doesn't lift the tire."

"They all treat the symptom—the dying grass. But the tire is still there. The tissue is still suffocating."

"What you need is something that opens the blood vessels. Forces them wide. Lets oxygen flood back into the starving tissue."

"That's vasodilation. And that's what magnesium does."

Dr. Marsten described a transdermal magnesium therapy he'd developed. Not a pill. Not an injection. A cream.

You apply it directly to the bottom of your foot. The magnesium penetrates deep into the tissue. Forces the constricted blood vessels open. Blood flows. Oxygen arrives. The tissue stops suffocating and starts healing.

"I tested it on myself first," Dr. Marsten wrote. "I had the same plantar fasciitis you have. Couldn't run. Tried everything. Nothing worked long-term."

"I used the magnesium cream twice daily for three weeks. By week four, I ran five miles pain-free for the first time in 18 months."

The article included a quote that Mark would never forget:

"The pain industry doesn't want you cured. They want you managed. Because a patient cured is a customer lost. Managed patients come back every six weeks. Cured patients disappear."

WHY THE INDUSTRY KEEPS YOU CYCLING

The article broke down the revenue model:

Orthotics: $400-$600 every 12-18 months. You need new ones when the old ones wear out.

Physical Therapy: $70-$120 per session. Most people need 8-12 sessions. Then they need "maintenance" sessions every few months.

Cortisone Injections: $200-$400 per injection. Work temporarily. Need repeat injections every 6-12 weeks.

Shockwave Therapy: $400-$600 per session. Most protocols require 3-6 sessions.

Add it up: The average plantar fasciitis patient spends $5,000-$15,000 over 2-3 years cycling through these treatments.

But transdermal magnesium therapy? One-time cost: $39-$78.

Use it for 4-6 weeks. Problem gets fixed. You don't need repeat treatments.

No recurring revenue. No repeat visits. No justification for expensive equipment.

From the industry's perspective, it's a disaster.

So they don't recommend it. They don't research it. They don't talk about it.

They keep you on the treadmill. Because the treadmill generates revenue.

WHAT MARK DID NEXT

Mark ordered Dr. Marsten's formula at 2:47 AM.

The package arrived three days later.

He applied the magnesium cream to the bottom of his foot twice daily. Morning and before bed.

Day 5: The stabbing pain in his heel lessened. Not masked. Actually lessened.

Week 2: The first-step-out-of-bed pain was gone. He could walk normally in the morning.

Week 3: He tried a short walk. One mile. No pain. First time in 18 months.

Week 4: He tried a slow jog. Half a mile. Slight discomfort but no stabbing pain.

Week 6: He ran two miles. Pain-free. Cried when he got home.

Month 3: He ran his first 5K since the injury. 28 minutes. Not his fastest. But pain-free.

Month 6: He registered for a half-marathon in March 2025.

That was six months ago.

Mark ran that half-marathon in March. Finished in 1:52. Not his personal best. But he finished.

"I got my life back," he told me in December. "Not just running. My identity. My mental health. My confidence."

"I'm down 28 pounds. I'm off antidepressants. I'm coaching my daughter's soccer team."

"The pain industry wanted to keep me cycling through treatments forever. Dr. Marsten gave me the one thing they couldn't: a cure."

WHY YOUR DOCTOR DIDN'T TELL YOU

I spoke to Dr. Jennifer Ross, a podiatrist in California with 14 years of experience.

I asked her directly: "Do you know about transdermal magnesium therapy for plantar fasciitis?"

"I've heard of it," she said carefully. "But it's not in our treatment protocols. We're trained to follow evidence-based guidelines. Orthotics. Physical therapy. Cortisone. Surgery if needed."

"Those are the covered treatments. Those are what insurance pays for. Those are what we bill."

I asked if she'd ever tried recommending magnesium therapy.

"Once," she said. "A patient asked about it. I told her I couldn't officially recommend it because it's not FDA-approved for plantar fasciitis. But I said if she wanted to try it on her own, I wouldn't stop her."

"She came back six weeks later. Pain-free. Stopped needing appointments."

"I was happy for her. But that's one less patient generating revenue for the practice."

THE TRUTH DR. MARSTEN WANTS YOU TO KNOW

I contacted Dr. Marsten for this investigation.

He confirmed everything in his original article.

"The pain industry is built on recurring treatments," he said. "Insurance companies love it because they can raise premiums to cover costs. Clinics love it because it fills appointment slots. Device manufacturers love it because you need new orthotics every year."

"Nobody profits from a $39 cream that fixes the problem in six weeks."

"I created this because I was tired of cycling patients through treatments I knew wouldn't cure them. I wanted something that actually worked."

"Has it cost me professionally? Yes. Some colleagues won't speak to me. Some clinics banned me from presenting at conferences."

"But I don't care anymore. Because I've seen 11,000 people get off the treatment treadmill and actually heal."

MARK'S LIFE NOW

I spoke to Mark one last time in December, 10 months after he started using magnesium therapy.

"I ran 8 miles yesterday," he said, laughing. "Eight miles. A year ago, I couldn't walk to my mailbox."

"My daughter asked me to run a 10K with her in February. I said yes. We're training together."

"I threw away my custom orthotics in July. Don't need them. My wife uses the night splint as a doorstop now."

"The pain industry wanted $8,000 from me and gave me nothing that lasted. Dr. Marsten charged me $39 and gave me my life back."

WHY I'M WRITING THIS

I'm a journalist. Not a salesperson.

I don't work for Dr. Marsten. I have no financial stake in his formula.

But after investigating the $47 billion pain industry, after speaking to dozens of people who spent years and thousands of dollars cycling through failed treatments, I believe:

The system is designed to manage you, not cure you.

Because managed patients generate revenue. Cured patients don't.

Mark Sullivan refused to accept that.

He was told to keep cycling through treatments that didn't work.

He found a doctor who told him the truth instead.

And now he's running again.

You don't have to stay on the treadmill either.

How Readers Can Access Dr. Marsten's Formula

After completing this investigation, I contacted Dr. Marsten one final time.

"I'm not trying to compete with the pain industry," he said. "I'm just tired of watching people suffer while the industry profits from their pain."

"If your readers want access, they can order through our website. We ship within 48 hours."

"But I need to be clear: We can only produce 600 units per week. When we sell out, there's a 3-4 week wait."

As a journalist, I can only report what I've found.

But I can tell you this: The pain industry wants you on the treatment treadmill.

Dr. Marsten wants you off it.

I’ve got it and honestly it’s helped me a ton. Been dealing with sciatica and an L5 S1 herniated disc for like 15 years. Tried everything you can think of… Gabapentin, acupuncture, inversion tables, you name it. I was this close to scheduling surgery but decided to give this a shot first and wow. Every time I use it I can feel my back warming up and releasing Hard to explain unless you’ve felt it, but man… it’s a game changer!

Right now, you're at a crossroads.

Path #1: Keep Doing What You're Doing

Keep popping pills that destroy your liver. Keep paying for injections that wear off in 9 days. Keep sleeping in that weird position that sometimes helps. Keep missing out on life because movement equals pain.
