I have two scars on my forearm unfortunate to say both are self inflicted. They are from 6 months ago and I'm noticing they are starting to bulge out. If at first started on one side of the scar but I recently noticed now the entire thing is risen up and the other is as well. They do not itch and Im not really concerned, more curious as to what may cause this?
(I would like to state that I no longer self inflict, I am going two monthes clean since I found out I was expecting.)
