I genuinely feel like I will have plantar fasciitis or feet pain for the rest of my life

I am now your doctor.

Take a full month off from running and do 60-90 mins of ARC Trainer, spin bike, or even swimming, whatever does not irritate it. Build your PT exercises up but make sure you aren't irritating it. And lift weights, get jacked and shredded. Eat enough food, healthy whole foods not crap. Take vitamins and magnesium supplement and collagen too. After that month, start adding running absurdly slowly like a few extra minutes each day and subtract those from your cross training hours each day so you still do 60-90 mins of cardio.

You'll receive your invoice in the mail, appreciate your business.

I had several doctors diagnose my heel pain as plantar fasciitis.
I had it for about two years and it got so bad that I could not stand for very
long and could not walk even half a mile. Doing the usual treatments did
nothing to help. Running was out of the question. I previously ran about 70
miles per week. Then I went to buy shoes from a former marathon world champion
who is also a physical therapist, and he said I did not have plantar fasciitis,
but rather tarsal tunnel syndrome, caused by forefoot varus. I placed a shim in
my forefoot to correct the varus, and I was running pain free in about three
days. That was years ago and I have been running without heel pain since. You
might check out videos online that describe tarsal tunnel syndrome and how the
symptoms differ from plantar fasciitis just in case you are also being misdiagnosed.

I already took 9 months off from running

Chronic injury? More like Chronic Complainer! Ha, but yea I agree with this guy….just stop being a whiny little child. Figure it out, and stop trying to find your answers on a letsrun thread. Why don't you do some research on what Alan Webb used to do to fix his feet. Although, that would require effort on your part, and it doesn’t seem you like putting that in.

Watch the youtube video posted by AthleanX (Jeff Cavaliere). i struggled with plantar for 9 months and then watched his video on plantar and was pain free in a week after following his advice fully. no joke.

Ultrasound, my man. Ultrasound.

you are screwed ngl

Bro, BRO. It's therapeutic to complain, I get it. But either your problem can be fixed or it can't. You're 24. Probably better to believe your problem can be fixed. Good to acknowledge that what you've tried hasn't worked. But it may just be a matter of degrees of treatment: you need more PT, more rest, or both. Or you need to start from scratch with new docs and therapists and treatments and try those. Even if they're all quacks, that's gotta be the play here. Those are your options. You can either change it or, you'll find, you can't. Change it if you can, but come to terms with it if you can't...

Have you considered a wheelchair and training for racing in those?

I hate to be the one to tell you but it takes about 12 years for PF to be fatal. It seems like it’s already traveled to your brain. Within 4 years you’ll be bedridden and it goes downhill fast from there.

Have you had quality orthotics with a horseshoe heel made? What part of the country do you live in?

Have you tried extensive stretching and strengthening of the muscles of the foot and leg?

It could be a nerve problem. It could be a lot of things…

Was there a specific moment or injury that caused it to start giving you problems? What shoes do you wear on a daily basis? Are you running currently? Is there anything you are currently doing that alleviates the pain at all, even a little bit? Does it feel any better if you walk without shoes, or walk on softer surfaces?

calf raises and as much lifting as you can that doesn't hurt it.

No one is going to know what you need to do and how long it will take for you specifically to heal if that is even possible.

If I were dealing with chronic PF, I'd be using a MOBO board daily, doing slant board calf raises barefoot using a tib bar and most importantly to me doing a series of isometrics stretching the plantar fascia against a resistance twice daily. And I'd be in the mindset to do this for years if necessary.

Plantar pain can be stubborn. I was on the verge of giving up resolving my issue when I took one last stab at a fix: progressive strengthening of my entire posterior chain and toe mobility. Just because pain is presenting in your plantar or achilles doesn't mean the source of the pain is not a weakness somewhere higher up: your soleus, hamstrings or your butt, for example. I recommend E3 Rehab's workbook on Plantar Fasciitis.

And even if you never fix it, your life is still full of meaning, and that worth a lot more than a healthy plantar tendon without a meaningful life.

Skill issue.

get some orthotics. case closed.
