Do i have a brain tumor?

I have no idea what it is wrong with you - but I once had similar symptoms. Toothache going right into my ear, really painful scalp - I couldn't bear to touch my hair - and underlying pain. There were various other things and I was in pain and felt ill. It turned out to be shingles but the symptoms were there before the rash. As soon as I got the treatment for shingles I started to feel better. (It was along the trigeminal nerve.)
