If you're not able to see a doctor, I would recommend that you go to the pharmacy to buy a medication over-the-counter called AZO. This can help to stop a burn from the infection. You can also buy an over-the-counter cranberry supplement to see if it clears up the infection. If you start to have fevers or feel sick though, there's no other choice except to see a doctor for prescription for antibiotics. Hope this helps.
