I had a bladder infection that went septic last July and I am experiencing the same symptoms right now, bad headache, pain between my shoulder blades, constantly urinating with little or no warning, can t urinate sometimes or urinating lot, then half hour later, needing to go again, can t stop it, sometimes the hair on my arm stands up when i am trying to urinate and I am in extreme pain, skin on back to sensitive to the touch, dizziness, sweating profusely and freezing cold... I think I need to go back to the hospital before it gets worse
