For three years I have suffered with chronic bladder pain. My symptoms are pain when peeing almost constantly teamed with every 4-5 weeks going through a bad bout of around 4 hours of excruciating pain to the point I get really hot and my bladder feels Inflamed and full and I can’t do anything but sit on the toilet crying and wincing until the pain eventually eases and burning when I pee stops (normally 4 hours). I have been referred to urology and had two cystoscopys both of which said bladder is fine. I have also been perscibed countless antibiotics for bladder infections. I am on the depo injection so haven’t had periods in years as this stops them. It’s only as I’ve stumbled accriss this site (whilst in agony looking for answers) that I’ve thought endo could be what’s causing it? Has anyone else had an experience like this? Thanks so much!
