I was just wondering how long it takes for scar tissue to go away. I think i have alot of scar tissue building up in my glutes. I find it reallly hard to push the needle in anymore. Before, once i broke the skin, that puppy would just slide right in all the way. Now its like once i break the skin, i have to push the needle in hard as hell to get it all the way in. I hit delts also, but they are fine, i like them the best.
