Hi! I’m a 17 year-old female. I don’t take any medications and I don’t have any health conditions as far as I know. I’ve had this weird lump on the back of my head for more than 1.5 years now. To begin with it would bleed and leak pus, but for a long time it hasn’t done either now. It’s a firm lump that moves around under my skin and hurts when I press on it, but I don’t notice it otherwise. I haven’t noticed any other weird symptoms. I think the lump is about 1.5-2 cm in diameter.
Is it something I should worry about? Could this be a cancerous tumour or something else that is dangerous? Should I see a doctor?
