I have tried it for Plantar Faciitis—back in '08 or so. They put me to sleep for it. Didn’t work. Hurt like hell when I woke up, and for days after. Felt like someone had repeatedly slapped the bottom of my feet with the principal’s paddle—hard!
I gave up running/racing for 10 years instead of trying that again. The stats for it with PF weren’t great; something like 1/3rd success rate for first treatment, and decreasing from there. I don’t know the stats for treating knee tendons—but I would ask before doing it, that’s for sure.
I have been down your path before with almost the same sequence of ITBS on one side, to the other side, to PFS, to Patellar tendonitis. Its insideous, and incredibly frustrating…not to mention expensive, often with limited results even from skilled specialists.
I’m not a Doctor, or any other type of medical professional. Most people tell me I’m too conservative. But, here is what has worked for me:
stop running. Replace it with walking. Vow to never run through pain, ever again. Don’t run while taking any type of pain killer (NSAID or tylenol)–those just make it possible to run through pain…you might not “feel it” but it is still happening (see above). Take the drugs if you need them, or are told to. Just don’t run while taking it.
I was given static stretches to do. the “lean into the wall” stretch, and the “cross your legs and touch your toes” stretch. Never stretch to cause pain. If it hurts, back off. tightness is good, pain is bad. Be gentle, and patient. I was told to hold each position for 30s, and repeat 3x. I know I was given strengthening exercises, but I don’t recall. I’d just keep doing whatever you were given.
After you are asymptomatic, and you ready to return to running: Start with very small amounts. I started with 5 minutes. And VERY gradually added single minutes week by week. It sucks, and it takes a long time to get “back”. Maybe there is a faster way, but I never found one.
If you EVER feel a twinge of ITBS coming on, STOP, and stretch. There is a reflex arc that happens, your ITB starts to tighten up as the pain comes on. That tightness causes more rubbing and pain, etc. So, stop and stretch. Let the ITB relax, then resume running…cut it short, and go home. when I was going through this I would basically do very short loops close to home so that I could just walk home, if needed. I did that until I was confident that I was over the hurdle and back to “normal”.
My rule for overuse injuries is: take 1 week off the first time it happens. if you try to train through it again…take two weeks off. Take an extra week off for every time you train through the same injury.
