Hi and welcome to HCM. Commonly thisis caused by cystitis which isis an bacterial infection and it must be treated with antibiotics. Oveerreactive bladder is another thing but it may definitely contribute to higher risk of bladder inflammation. This is also a common and often embarrassing problem. If overreactive bladder affects your daily activities, don t hesitate to see your doctor. For most people, simple lifestyle changes or medical treatment can ease discomfort. It is treated with specific medications, pelvic floor muscles exercises, electric stimulation of bihevioral treatment and in most cases this is adequate for incontinence control. Surgical options are reserved for severe and intractable cases. I hope I have answered you query. If you have any further questions you can contact us in every time.
