The bump started small and I though maybe it could be an ingrown hair. So I then plucked the hairs surrounding it and I may have irritated it because it got bigger. I have been to the dermatologist twice and inject with cortisone. It has not gone down in size. The main portion of it feels like it is full of liquid and is about just under the size of an eyeball. Right next to it is a hard pea sized growth. I am on Accutane so I can not have it surgically removed. Can it be drained? Should I be worried about it being cancerous? What do you think this is and how can I get rid of it or reduce the swelling? Thanks so much for your help.
