Has something in his diet changed or soap, after shave, Does his tongue swell
I suggest he should see an Allergist and or a Dermatologist!
Ive had something similar happen too. Out of nowhere my lip started swelling. Ive had it happen several times. I know its some sort of allergic reaction but it could be from almost anything. I say see an allergist as well. good luck
I have had the same exact thing for 3 yrs....I have tried the allergy specialist done the testing and nothing conclusive. I take Zyrtec and Zyzol no help. The swelling can be in my face, feet or arms....all I hear is its idiopathic recurring angioedema......I WISH WE COULD FIND AN ANSWER!
