Gina, personally I'd be really skeptical (and SCARED!!!
) about buying medicine online...especially without a prescription. Not only do you not know what might be in the medicine or how reputable the provider is, but you also have no idea how it might affect you.
Please do go see your doctor, okay?
I think it's great that you have a better idea of what's causing the problem and have done some research so you will be better informed when talking with your doc. But you could easily have missed something important. Don't take that chance...talk with a professional and make sure, okay?
Let us know how it goes. Hope you feel better soon!
