I had a c section 4 months ago. Since then I have suffered with a burning sensation right at the end of urination which is slightly relieved if I drink a lot of water and no caffeine. I have been treated for thrush and the doctor has confirmed I do not have a UTI. The burning sensation gets very severe the day before I start my period and then for the whole of my period I have absolutely no burning sensation. The day my period ends the burning sensation returns. Any help would be really appreciated.
