Conditions such as bladder cancer or urinary tract infections can sometimes cause bladder pain, according to WebMD. Another common cause of bladder pain is interstitial cystitis.
The most common type of bladder cancer is transitional cell carcinoma, states WebMD. This type of cancer occurs on the innermost layer lining the bladder and can cause additional symptoms such as blood in the urine, pain while urinating, frequent feelings like one has to urinate or lower back pain.
A urinary tract infection happens when bacteria manage to enter the otherwise sterile urethra and continue to the bladder, which can cause infection, according to WebMD. Along with pain in the bladder, a UTI can cause pain while urinating, cloudy, bloody or foul smelling urine, urgent feelings like one has to urinate and a low-grade fever. Antibiotics are the primary means used to treat UTIs.
Interstitial cystitis is a chronic condition where the bladder becomes inflamed, states WebMD. The inflammation causes the walls of the bladder to become rigid, which makes it difficult for the bladder to expand when filling with urine. The primary symptom of this condition is pain, especially when the bladder is full or filling. Medications, such as antihistamines or antidepressants, may be effective in relieving pain associated with this condition. However, the specific treatment depends on how each individual responds to different drugs.
