Last year I had swelling of the lips - both upper and lower. I went to my Dr and he said it was a food allergy. I was tested, but nothing came of the tests. This year, at the same time of year it is back. I have not changed what I am eating. I have a convertible and in the beginning thought it might be sun or wind burn because I was not wearing a hat or a visor. I have been wearing a visor for over a month, and last week did not put the top down on the car at all. No change - in fact woke up Friday with them the worst they have been this year. I am keeping Carmex, Blistex or a tri-biotic ointment on them at all times. I have also tried to take Benedryl, but cannot take while at work - only at nite. Do you have any suggestions? They are worse in the a.m., but today have been painful all day.
