Yes I had a endoscopy done a week ago and after two days started having breathing difficulties wheezing and coughing went to Dr said I had bronchitis. Im wondering if they could of aggravated something in my bronchial area to aggravate this. Was fine till I had the scope. My Dr said I was probably coming down with something before I had the procedure. I was put on antibotic, a inhaler and  a steroid for 9 days Im 4 days into steroid and still wheeezing
You must have been allergic to the local anesthesia used for endoscopy it takes 4 wk to subside by medicines in Chat Doctor.
