I have a mole right below one of my eyebrows, recently I noticed it swelling out a little more each day, then a small black dot appeared on the tip of it. Yesterday it started to itch really bad, and when I scratched it the black dot fell off, and the swelling went down. Now it's not the same color as it used to be, it's a weird brown color. It doesn't itch anymore thoguh. Do you think I need to still have it checked out? or do you know what it may be that made it swell like that?
