On and off swollen lips moving from side to side.  Swollen face, itchy welts on head after taking Benadryl.  Allegic reaction?
Patient: I recently had a weird experience, like an allergic reaction, to my lip that swelled up overnight for no apparent reason.I am 69 and healthy.  I have been traveling to visit friends and then once again I had a swollen lip that moved from side to side??? Then I took a benadryl and then I had itchy welts on my head.....today better, but still swollen in my face.  Teeth are fine? Doctor: Hello,Thanks for posting your query.Swollen lips as well as face can occur usually due to any infected tooth underlying.The swelling may not be associated with allergic reaction of the drug administered.Get a thorough evaluation by a dentist.Infected tooth has to be root canal treated or extracted depending on the severity of infection.Usually antibiotics/antihistamines has to be administered.Discontinue use of  Benadryl and get it replaced.Hope i have answered your query.Take care.
