I have got yet another diagnosis and now it is confirmed. My semitendinosus tendon did not grow back. I blame it on hamstring exercises that my physio made me do only one week postoperatively and onwards. It involved hamstring curls with weights.

This came as a shock to me even though the doctors tell me that I will be able to run without this muscle. I really want the muscle fixed. I wonder if prolotherapy can help. Otherwise I may consider tendon reconstruction with an allograft.

I need to work on the hamstring now since it is very weak. I experience spasms in the semitendinosus in hamstring curls even when only using minimum possible weight.

All advices and information about my considerations are well appreciated. Also some tips on hamstring exercises. I dont know whether I should work more on the weak hamstring than the healthy one, or keep it balance. Should I do training everyday, or more intensive training 3-4 times a week?
