I just read your other post titled "bloody urine". You said dr found red dots on your bladder lining, no infection, no kidney damage, etc.
Have you heard of "interstitial cystitis"? It is a rare bladder illness. Patients get cystitis like symptoms.Cystoscopy usually reveals a red inflamed bladder lining (such as red dots) in the absence of bacteria. Ask your dr about interstitial cystitis (IC). Many drs rule it out so fast as it is a rare disease. By the way, it has nothing to with cancer and it is not life threatining. It is more of a nuisance than anything. I am not sure if you have IC but it is worth looking into and its symtoms are treatable.
Hope this helps.
