Doctors

My random thought of today has to deal with doctors and their offices. In September I got sick and the dr put me on biaxin and then my period started. Well, with my period came some tenderness(raw) and it hurt. I didnt put two and two together until this last time. Right before thanksgiving, i went into the dr again and she gave me biaxin and it happened all over again. I made the connection. So today I called my ob/gyn because it hurts alot down there when i go to the bathroom. I wanted to schedule an appt, but no I have to leave a message for the nurse and probably won't here from her until who knows when. Why is it they can't just schedule an appt?
