It seems odd that they have not checked your kidneys! It sounds like a kidney infection to me which explains why the anti-biotic helped. I used to have horrible kidney infections when I was in my early 20's. You will want to get it taken care of because it can cause lots of issues! You really need to see a normal doctor instead of emergency room because you need someone who is going to test and try something, see if it works and then try something else.
Good luck!
