I've had a cystic pimple on the underside of my jaw for about 6 days. This started growing after I pulled some hairs from the same area. Warm compresses 3-4 times a day and still no head. Feels like a rock maybe the size of a pearl. Reddened around the outside but inside there's a definite area of yellow which move and changes position if I put the tiniest pressure on it. Do you think its time to go to a derm? If it wont come to a head could they lance it just to see what the heck is in there. Never got a cyst from pulling a hair anywhere on my face. Could the hair follicle be infected or blocked? Please help.
