I have recently been hospitalized with a virus of some kind which caused a UTI, fever blisters, and left me uncomfortably near renal failure. It was complicated by an exacerbation of my COPD, and left me disoriented, and weak. Since being released, still on prednisone and antibiotics, I have developed an aching in my jaw when drinking liquids, feeling like you have sucked on lemons... I am now running a low grade temp and have caustic diarrhea which cause a burning in my rectum...
