Hi Dace
I met an orthopaedist who told me this.
The semitendinosus muscle is very stiff at all times. And I can move it a bit to the sides. No stretching or massaging has helped.
A surgery seems to be the only option.
I am wondering if improper rest after the acl reconstruction operation could have played a role in this. Only 5 days after the operation, I was back to (office) work. However, I read it takes 6 weeks for the harvested tendon to grow.
Thanks for your good wishes,
Arni
