Hamstring injury from cycling

Hi everyone, I'm writing to see if anyone has experienced a similar injury to me. A year ago I tore my hamstring whilst cycling, which from a recent ultrasound appears to be a grade 2 tear. I probably did not take the injury serious at the beginning, and after resting for a short period carried on cycling.

After consistent pain I have been having physio since approx February, focusing on stretching, strengthing and massage. Symptoms improved but not hugely. I was able to ride gently throughout the summer without pain, but unfortunately damaged the hamstring again after a somewhat hilly 50 mile ride.

After rest and more physio, injury seems to have overall not improved since. Ultrasound has shown there is large amounts of scar tissue in the area, which is proving hard to break down. I have now stopped with even gentle rides.

Has anyone had a similar injury? It's been a year now and I feel like I'm making little progress, if any.

Thanks

Which part of the hamstring is it? Have you had a bike fit? If set up correctly your hamstrings should never really be in a full extension (never mind tearing) on the bike, so that’s quite interesting. Not very helpful, I guess, but I’m curious.
