I have 2 large brown lumps (one cm and the other half a cm) on the back of my scalp that have been there for a year and a half. I have been worried about it nonstop and I have tried countless times contacting a GP to get it checked, everytime I try to book an appointment I get told because my symptoms are not acute I cannot been seen to. I even changed GPs and got told the same thing. Is there some way I could get it checked or get advice on what to do.
