Hi.

I have a burning sensation when urinating. I have been checked at std clinic several times and have had the all clear. Its been happening for a few yrs now. My gp has no idea what it could be but has suggested it could be a damaged nerve and is sensitive. Some 1 help please because its really doing my head in and getting me down.

Time to get checked out by a urologist.

I, too, recommend seeing a Urologist. You may be suffering from a low grade prostate infection call Prostatitis. Here's a link that describes the condition and symptoms. Prostatitis Causes, Symptoms, Diagnosis, and Treatment Information on MedicineNet.com
