It sounds like a Keloid scar, I get those all the time it takes a while for them to go away but if you massage it daily with lotion for strech marks it contains vitamin E and collagen to give more elastisity to your skin, scars lack elastisity which is why they some times seem bumpy or purple, it's not the same as your regular skin. Hope this helped! I got this info from a doctor friend, when I asked about my own raised purple scar!
