Good advice. Heat pad on bladder area helps as well.
it could be so many things...the blood in the urine could certainly point to severe UTI, Interstitial cystitis, endometriosis...I have blood in my urine and have IC and endometriosis...I also have pelvic floor dysfunction (the spasms) PT did not work for me but is definitely worth trying! I use vaginal valium and have an interstim placed...it helps some...could you have a bladder prolapse? since you are seeing a urogyn they would be able to tell you...in the mean time try to calm down as the stress and worry will only make the spasms worse..try epsom salt baths to relax the muscles of the pelvic floor, heat packs and elevating the knees higher then the hips as this makes the pelvis relax...if your urethra feels it's on fire...take a frozen bottle of water and place it in the area of the urethra (with clothes on between your skin and the frozen bottle-no frost bite down there please!)
these are some of my tricks...also, make sure your diet is very alkaline...stay away from acidic foods...and it never hurts to get a second opinion...so get copies of all your medical records and seek a second opinion!
