While playing squash 4 weeks ago, I made a false step and felt a snap in my hamstring. There was no immediate pain associated to it. However, when it cooled down, it made me limp a bit.
From what I read on the net, this is maybe more than a pull, but not a severe tear.
I've rested for the past 4 weeks, and I'm not sure it has healed. When I stretch it, I feel a sort of 'knotted' muscle sensation right above the knee on the backside. The pain from stretching is a bit more acute than what I would feel while stretching my healthy hamstring. However, I can almost achieve normal mobility with it.
How can I tell the hamstring is healed, and the pain I feel is not simply coming from the fact that the leg was injured and inactive for 4 weeks, thus being harder to stretch ?
