so I was admitted into the hospital last weekend for a kidney infection and yesterday night made a week since I was released.. Was sent home with more antibiotics, we'll yesterday was my last day taking them... Today I've been miserable again: pressure and pain in low abdominal area more back pain although my back pain never went away fully, nausea, vomiting and head ache. I have an appointment Friday to make sure infection has cleared, should I wait for my appointment or go back to the er??
