flexor hallucis longus (FHL) tendonitis

I had this same problem and thought it was PF as well. I went to PT for about 6 months and it finally got better, but I wasn't running hardly at all. I didn't get any pain in the ankle though. Try bending your big toe back to your shin--if you feel it then, it is probably your FHL.

Most of the PT stuff was similar to treatment for PF--picking stuff up with my toes, stretching my calf and soleus. I also had electric stim. It was a long process.

As far as stopping running, I had to for awhile, but you might be able to train through it. I wasn't training for anything particular, so I didn't mind the cross training. Best of luck.

Thanks for the advice. I'll start stretching the calf more, I have noticed it being tight. Would putting on an immobilization boot be worth a shot?

I have tendonitis in my FHL. What did you end up doing to treat yours and how long did it take to return to running?

Been having similar problems. Best solution is to get trigger point massage/have someone do acupuncture that works with athletes. Works very effectively - forget about immobilization boots and that other crap. Good luck.
