Thanks Canuck!

Yes, I'm getting treatment now. I'm on indomethecin for the osteitis pubis. I'm focusing my core workouts around a protocol groin injury designed for Major League Soccer players. I've got an appointment tomorrow with a physical therapist who specializes in the pelvis.

I'm curious if there's a connection between the adductor tendonitis/alignment issues and the hamstring strains, but no professionals have suggested a link.

I'll plan to get my hamstring stronger than they have ever been before returning to sprinting. I'll do the standard physio hamstring protocol and, later on, weight training.

Do I need to work in any hamstring speed exercises before sprinting? Or is power and endurance sufficient? Therapists have recommended easing into full sprints but haven't recommended any particular remedial speed training exercises.

I hadn't thought of a biomechanics assessment. I'll give that a try. Great call!

Another thought: I've read a bit about adverse neural tension and lumbo-sacral nerve roots causing hamstring problems. (Mostly they cause pain and feelings of tightness but can cause the strain in some cases. I'm not sure if I'm reading the literature correctly, here! I'll try to get someone to do the "slump test" on me.) Could any of these problems be causing parts of my hamstring to misfire, leading to strains?
