Infection? You may have a urinary tract infection. If you can take over-the-counter Azo (or other urinary tract analgesic) and it helps, then likely that is what is going on and you need to get checked and treated promptly. It could be something else and the only way to figure out what's going on is to see your doc. If you have fever, vomiting and pain in the mid back (over your kidneys), call doc or ER.
