Cystitis is an inflammation of the inside wall of the bladder. There are various factors that cause the disease: bacteria, allergies to detergents, friction or rubbing of the urethra during sexual intercourse, bladder hypersensitivity, fungus and even anxiety and depression. The symptoms of the disease are pain like a sting or a strong burning sensation in the urethra during urination. Some patients suffer from a strong urge to urinate but when they get to the bathroom they have a very small amount of urine. The urge itself may occur very frequently, regardless of the small amount of urine that comes out.
