Well I've just had my appointment.
I was seen by two oral surgeons. The first said he couldn't feel anything so went and got his consultant, who had a feel too. He said he COULD feel a lump but said he wasn't worried and told me he thought it was a tonsil. Apparently they increase and decrease in size now and again. He said that if it continues to bother me, then to make another appointment and they'll sort it out for me.
Hopefully he is right and that's all it is, I'll try to forget about my mouth for a week or so (that means no touching Aimee), and see if it decreases in size. I think has a bit, it's weird. It kinda gets big and a little firm and then I get the strange sensation in my mouth like something. Has burst then a slightly funny taste and it feels a little smaller, think its done this twice now.
