go to walmart or any drug store and purchase AZO if you cant get to a doctor... its the same as prescription pyridium... which treats the pain quickly and helps flush your system of the infection.... but also drink lots of cranberry juice... this is what i used to tell patients that were unable to come into the office, and have done it myself :)
Sounds like an UTI. Do the doctor's appointment. However, I had a UTI a couple months ago, and I cleared it w/o a dr visit or antibiotics. I drank lots of sugar free cranberry juice and lots of water.
