I found this lump behind my ear... it's on my head on the bone, sorry can't describe exactly where. I noticed it by accident about a month ago when I went to scratch my head. It's still there and feels like a pea size lump under the skin. I am not sure if it could be a cyst or something. I am a little worried since it is still there. Does anyone have any ideas what it may be? I am seeing my GP on Fri so will mention it to her then I guess. I feel a bit silly really but I would rather be safe than sorry.
