Hi sorry you are going though all that i'm afraid i will be be on cycle of different meds also.I got urine test results negative.I also get pee urgency with no burning also feel a little aching which seems to get worse afternoon and and night it will start up with feeling like my vagina burning the most annoying feeling have to use ice pack or heat pad when i go to bed!!Do you take a probiotic i have been taking for years.So i will be going to a gynecologist i will try and find a uro one.Unfortunately i think most doctors feel its in our heads.I was very happy before this doing my workouts walking and do yard work don't know if i did too much which might of caused a swollen urethra.Could the stitch be hitting something?
