I had an accident around 15 years ago which left a second-degree burn and a scar just under my right shoulder which still remains. It's roughly as wide and round as a palm of a hand. Thing is, I have been working out a fair bit for the last several months and have been noticing some uneasiness when I do certain movements around that area. It feels like it's trying to stretch itself out along with all the other skin around it (as I bulk). I'm only 21 now so I have obviously grown a fair bit and I haven't had this problem before. But could it be because it is unable to stretch as quickly as I want it to and in response the scar is causing touches of pain every now and then?
