Thank you both for replying.

I'm going to have a trip to A&E and see if they'll have a proper look at it for me and actually get a referal or see if I can convince them to get a scan or biopsy done then and there, though that is very doubtfull. I had bloods done about a month ago for my thyroid, liver, kidneys, glucose and a full blood count and they all came back clear.
