question: I had an allergic reaction to a sulfar based antibiotic that caused kidney failure. I am getting better but my nose and mouth feel numb as if I had a shot from the dentist. This happened on Sept. 22, hospitalized for 3 days. The hospital did all types of test from CT scan, MRI, EKG, etc. nothing indicated a problem such as stroke. I am getting stronger every day. However this numbness that feels like nose and upper left lip, especially nose feels strange, nasal secretion. No one seems to know what is causing the problem. I am having a gastroscopy procedure done on Wednesday. All of this started because I was diagnosed with bronchitis 3 times this year. I have problems swallowing and coughing. Should I be concerned?
