• Inner thigh stretch mark bump?

I gained a decent amount of weight over the last 2-3 years. After I have started to workout and eat better I still got a new stretch mark on my inner thigh (was getting them while gaining weight as well) this new one however has a small purple line that is under an inch in length but the area around and including it is raised and dense. Alone it doesn't hurt but direct pressure stings like a localized intense bruise.
