Facial swelling. I think it could be due to the eye gel-Refresh Liquigel, from the opthalmologist. Used only one night and the following morning, the itching started and around 7:30pm I took one benadryl tablet and noticed it got worst eyelid swell. Area around upper lip felt swollen. Around the whole face is rash. Emergency dr. told me to take one more benadryl so when we got home at 10pm, I did and went to bed. I woke up at 4am and it gotten worse. The swelling and puffiness on my eyelids and all over my face. Should I go back to emergency? Dr. said to go back should it get worse. It itches, no pain, only on my face. Pease help!
