Any suggestions on how to resolve high hamstring tendinopathy? I've been dealing with this issue for almost two years now. Basically I feel a sharp pain in my high hamstring / glute anytime I try to squat or deadlift. The pain gets worse with greater hip flexion (i.e. deep squat), heavier weight, and faster movement (so deadlifts in second half of 18.4 were pretty rough for me!). Once it is irritated from a heavy lifting session, even an air squat is painful for up to a week afterward.
I've been to a number of doctors and have been through multiple rounds of PT working on glute / hamstring strengthening, but nothing seems to relieve the problem. Are there specific exercises or stretches I should try to fix the issue?
