I am 45 and have run 5-6 miles/day for last 10 years. 3 months ago, for seemingly no reason, my psoas began hurting and getting tight. I found that I did not have pain with walking or running, but tremendous discomfort and tightness about an hour after any exercise. This pain now is in my glutes, back, and have trouble sleeping due to discomfort (up 4-6x/night) I ve been to numerous chiros, massage therapist, been stretching, been strengthening (according to chiro s instructions). The only relief I have found is the Mobic my Sports Med Dr prescribed, but no real improvement (cannot come off Mobic without returning to the steel girdle feeling and back pain). A new chiro has suggested a full workup with my OBGyn/ ultrasound ovaries. I m confused... is this a muscle, back, or ob/gyn issue?
