Again I thank you all for your responses, they have been very helpful. This is the last time I will bug you all before I get to an oral surgeon or ENT who can help me get a diagnosis.
I was reading through my medical journal, which I kept for a month or two back when all of my symptoms started, and I was taking pretty thorough notes. I mentioned a lump I felt on my throat. I had a GP look at it and she massaged it thoroughly and concluded I had a more pronounced adam's apple. I didn't see any reason to disagree at the time as I didn't know if it had always been there. This was around the time I found the mouth sore.
Anyhow, my point is that I am having more throat symptoms now, and I had forgotten I raised that concern previously. Tonight I feel as though someone has their hands wrapped around my neck. Additionally my face feels weird, like the skin on it is tingling at times.
I don't really know what my point is, I suppose it is that the more I think about all of this, the more I realize I should have pushed harder several months ago. I didn't know I needed to. I know everyone's motto here is that it isn't cancer until a biopsy says it is, but I'm coming to a point where it would literally have to be a combination of some pretty weird stuff to be anything else. Believe me, I've looked for other stuff, extensively.
At any rate, thanks for the kind wishes, advice, and warm thoughts. I will let you know when I know.
