Is it normal to have scar when no injury or medical procedure?
There is a scar 18 mm long by 5 mm wide that appeared on my left arm two days ago. I have had no medical procedure, no injury to that arm. By the size of the scar, if I had an injury I would know it and there would have been blood. The arm is not sore at all. In fact, if I didn't see the scar I would never know it is there. And whats more is that I have had my share of cuts and scrapes and I know that a wound of this size takes time to heal. It is a process. Part of that process is a scab which takes about two days to form, then hardens and stays for about a week until it eventually falls off, leaving a scar. But in this case that did not happen. Arm was normal one day, the next day there is a scar. Anyone else have this happen to them?
