So I pulled my my hamstring back in early February(well, I was running sprints and it popped and I couldn't really walk afterward). While I can now walk, jog, and lift now, it doesn't feel 100%. I can still feel a hint of pain deep in the muscle if I flex it and it feels tight on good mornings and similar movements. Does my diagnosis of a pulled hammy sound right? How long do these usually take to heal?
