Does anyone have any experience with what seems like muscular pain the buttocks/leg/lower back, but only on one side? Went for a six mile run this past Thursday and upon finishing I was immediately hit with pain in what feels like the left buttocks, left lower back and part of my left leg. The pain left me limping around the rest of Thursday and all of Friday. I took Friday off but foolishly went for a long run on Saturday, thinking I could fight through the pain. Barely finished but had to stop multiple times to stretch out my left leg. Could barely muster 7:45/8:00 minute pace for a run I would've normally hit sub 7:00 for. Have been limping around all weekend, although the pain does seem to be decreasing. FYSA, the pain only seems to flare up when moving around. When I am sitting, I barely notice it. Does anyone have an idea of what this is? And what do I need to do to fix it? Not being able to run sucks ass.
For background, I was running 30-40 mpw and hitting the gym three to four times per week doing upper and lower body exercises.
