Here's the key: according to scientific literature, the grafts are secure after 9 days, let's say 10 days to be extra cautious. You may pretty much do as you please after two weeks.
The protocol might say don't exercise for 3 months - a ridiculous and unnecessary length of time - but I was back on tennis courts after about three weeks. Maybe it'll affect my scar or maybe not. I can't possibly be expected to do nothing for three months. I've consulted enough reputable HT doctors' protocols to know that normally you may begin physical activity: running, etc. after 2 weeks. The protocols are a general guideline and they aren't Gospel Truth. There's too much variety among top doctors. By the way, Dr. Rahal told me that I should wait at least three weeks before resuming playing tennis.
But no offence, in this instance you were careless and have only yourself to blame. Dr. Rahal is very ethical.
