Overactive bladder is not uncommon in women. Most of the time you have urgency symptoms but not bad pain. For example, ovarian cysts or bowel spasticity can cause a full feeling and urethral syndrome can cause a urethral urgency. The key difference between overactive bladder and interstitial cystitis is at night. Overactive bladder will have 4 or less voids per night while interstitial cystitis will have many more episodes of nocturia.
Overactive bladder is treated by anti cholinergic or anti-muscarinic agents.
Flavoxate does not appear to be very effective. Bladder frequency, urethral discomfort and low estrogen Is there a connection between uncomfortable bladder symptoms and the use of IM depotestadiol. When estrogens are low, the urethral mucosa gets quite thin and more prone to infection and irritation. The small bulge could be a cystocele which is the bladder itself or the end of the vagina, i.e., vaginal prolapse. If this is the case and you are having pressure symptoms or any difficulty voiding or initiating stool, then surgical repair will usually cure or decrease symptoms.
