I believe its a congenital melanocytice naevus (based on what i've read). Its on my arm and has been exposed to years of sun exposure. Yesterday i felt a burning sensation on my arm and looked. Arm looked ok..but did notice that i had little black bumps in my birthmark that is normally a beige-brown color. It looks really dry but lotion didn't change the look. Hair is still growing there.
Is this cause for concern??
