Month or two ago I picked on my mole quiete alot.. i guess I irritated it cuz it bled the next morning then scabbed up. After that it looked like a just plain flat brown mole then.. now it is kinda lighter and darker in the center.. and it looks like theres a tiny pimple on it.. should I get this checked again? the last time I went the doc said it wasnt anything unusual (it is still round.. color is just little weird and that tiny pimple looking like thing) and I've had it since birth btw. (also nothing like burning/ itching)thx
