On Tuesday I went to the doctor for a routine visit, but i also had a bronchial cough/cold which had started a few days prior. I coughed so hard that I had white flashes and peripheral disturbances in my vision. Tuesday and Wednesday I had heart flutters. Tuesday I was given a flu shot and a a prescription for meloxicam, 15mg once per day. I took one on Tues. and one on Wed. but no more since i started feeling nauseous. On Tuesday evening my hands started itching SEVERELY....followed by feet and ankles itching horribly. Wednesday the itching continued and i started taking benedryl. I cannot go without the benedryl or the symptoms worsen. Yesterday (Saturday) evening, my lips swelled severely, the itching was horrendous, and my eye and cheek swelled. I took benedryl and it has subsided. Again, without the benedryl the symptoms return. Any advice?
