Hamstring problems on treadmill

This past summer I raced 12 times, did alot of kms both running (outdoors) and biking…no problems. Now I’m back in the gym running the treadmill and my hamstrings; both left and right are bothering me…feels like a pull on the middle of the hamstring about halfway up the legs.

Anyone else have this problem? Any suggestions.

Thanks

I’ve had similar problems in the past. We found out I had a back problem. A few months of PT and it was ok again. What finally drove me to the dr. was the fact that the pain never went away. It felt like a knot in my hamstring. Couldn’t get it stretched out. Hope that helps.
