hi, i've get these weird boil type things that are like square shaped and at first i thought they were boils but they all of the sudden start scabbing and profusely ooze plasma. i have one on my neck and it hurts so bad that it has been affecting the muscle next to it. i can't touch it with out being in excruciating pain. i also have some on my forehead that i thought were like pimples but 1. i dont get pimple and neither does my family 2. they just will randomly ooze that plasma stuff and then scab horribly.

should i go to the dermatologist? i've been to a normal doctor and they always freak and say it could be ringworm (i dont think so) or skin cancer (i dont think so either because it comes and goes)

this is also fairly recent. past couple of months i would say.
