Hi,
I noticed a small black mole under my armpit two days ago. I've never had a freckle or mole this black. When I touched it, it hurt like a burn.
At first I thought it was a scab, so I only slightly scrapped it with my nail and it the black part fell off.
But there is still a mole underneath, half of it is very dark and half dark brown. I am concerned as it is still hurting, like a burn without my touching it, it is red around the edges now and sore. I barely touched it.
Should I worry?
