If your GP surgery or local council run a Well Woman clinic go and see them, this may well be something other than a UTI possibly hormonal. If no Well Woman clinic in your area and Your doctor is a little unapproachable, and no other doctor at surgery, try to see practice nurse, who is probably a trained continence advisor and well versed in all things bladder related. also don't use coloured toilet tissue, there is a small theory that the dyes used in toilet paper manufacturer can irritate, there is some difference of opinion on cranberry juice, but a small glass everyday may well help, it was believed to stop bacteria adhering to the bladder wall, but even if no proof it helps, a lot of woman swear by it. Put nothing in your bath water, and only use a specially designed wash for your intimate areas. If you are sexually active, your partner could be re-infecting you. There are so many aspects that you really need to speak to a professional who specialises in bladder and urethral issues. The average GP only has a limited knowledge about a vast amount of things and cannot always find the root of a problem, they cannot always sort something out. you really need a specialist in this field if this continues. I so hope you are more comfortable now, as these infections and conditions are really uncomfortable. Get better soon .
