I am 34 & have suffered from thrush since I was 19. However over the last 3 yrs I have suffered from different symptoms such as swelling, redness and a burn which can be quite painful at times. I usually get the symptoms at least twice a yr but at the moment I have had it since October 2009. I am not sexually active, since Sept 2009. I have been to the GU Clinic on numerous occasions, the last time being November 2009 where I had numerous tests, including thrush and everything came back negative. I have been to the Dermatology Dept where they perscribed me Piriton Tablets which havnt helped. I am due to see them again in 4 weeks. I really need some advice because it is starting do get me down now. Could I have an intolorance to something. PLEASE HELP :(
