Bladder infections can also cause back pain. This pain is associated with pain in the kidneys. Unlike muscular back pain, you might experience pain on both sides of your back or the middle of your back. Such symptoms mean the bladder infection has likely spread to the kidneys. A kidney infection can also cause a low fever.

A doctor can diagnose your bladder infection by performing a urinalysis. This is a test performed on a sample of urine to check for the presence of:

white blood cells
red blood cells
nitrites
bacteria
other chemicals that are present in the urine when there is a bladder infection

Bladder infections are treated with prescription medications to kill the bacteria and relieve pain and burning. Home treatments may also help relieve symptoms and cure the infection.
