B.P.
Do you drink a lot of sodas? I know that the sodium and caffiene (sp?) in them can cause similar problems.
I know that drinking LOTS of water and pure cranberry juice (like Northlands, but never Ocean Spray) can help the whole urinary tract. If you can't drink cranberry juice without all the extras like Ocean Spray does, you can get AZO tablets that are cranberry juice concentrate that promotes UT health.
Best of luck! If you can't rememdy the problem at home in a week, go see an different doctor. You don't want to make anything worse!
