Hi, thanks for the reply.

Fingers crossed you are right. My doctor is pretty understanding and knows I get a tad worried about my health, so hopefully it should take too much to convince her to give me a referral. I've not tried actually outright asking her for a referral yet, so may e that's all I need to do.

My dentist said he doesn't think the swelling is anything sinister, and thinks maybe I grind my teeth at night as I'm getting toothache on and off in my back teeth. He said I probably caught my tounge. I'm just worried as it seems too far back to be able to bite that part of my tongue and its been like it has for 5 weeks+ now.
