Hi. I m a 27 year old female, 5 4 weighing 9st 2. I ve been having recurrent urinary infections for about 9 months now. My doctor has given me a lot of antibiotics and referred me for blood tests for glucose , thyroid , liver & kidney and FBC. I have also been for an ultrasound scan on my bladder , urethra and kidneys. All have come back clear. Most recently my doctor has put my on a 3 month course of trimethroprim. I no longer have blood or pain when I pee but I am still suffering from a frequent urge to pee, and pain when I get the urge in my abdomen. I also suffer from IBS which usually leaves me constipated. I have noticed that when I am constipated this pain and frequency in my bladder is much worse and that after I move my bowels and finish up in the bathroom, I feel like my bladder is full again straight away. My perineum is also really swollen and has bled bright red blood a few times. It hurts to have sex. I have one sexual partner and don t have an STI. Thanks for your help.
