Have a 2mm black mole that appeard on my leg. looks circular but up close 1 side looks much different. picked at it&bled &pussed. small lump under?

Please get an exam: As above, until then moist warm compresses are fine and motrin type medication for pain control

Although at: your age serious "moles" are very rare you have most likely infected this one and now need it checked out by your Primary Care Provider! Hope this helps Dr Z BTW IN THE MEANTIME STOP "PICKING" at it! Cover it with a adhesive bandage and LEZVE IT ALONE until it can be checked out!
