My gp gets very cross with me for looking things up on the net - I always end up thinking I've got some life-threatening disease which is actually something very mediocre and easily treated
It reminds me of that Sex in the City line about typing in your symptoms on Google and waiting for the search engine to return 'CANCER'.
Robinw, I'm sure you are right in your diagnosis and hopefully it is benign but please go to your gp anyway!!
