Hello, I have a 9 yr old son that broke out with hives on the bottom of his feet on October 9th. The next morning, he had a high fever, & sore throat. This was on a Sunday, so we treated his symptoms, and took him to the doctor on Monday the 11th.  The tested positive for strep throat, and our pediatrican said that the hives were due to the strep.  She prescribed him amoxicillin (which he has taken many times before.) The next morning, he woke up with  a swollen bottom lip. (it was huge!) We took him to the emergency room, the gave him an epi shot, a dose of benedryl, and changed the antibiotic to Keflex, saying he had developed an allergy to penecillian.  The swelling was gone by the next morning, but that afternoon, he started to swell again.  We called the pediatrician again.  Took him back to the Dr. Office, they agreed with the ER docs diagnosis, and just gave him a steroid, & told us to do the benedryl.  He cleared up, and got better.  The monday morning (Nov 1st), he woke up with another swollen lip!  I gave him bendryl, and by tuesday afternoon it was clear.  He went back to school yesterday, and when we picked him up, his lip had started swelling again!  I am about to go nuts!  Can you help me?
Hi Dear, Welcome to Chat Doctor. Understanding your concern. As per your query you have swelling on lips after fever which could be due minor dramatization of blood vessels which keeps on forming small spots on lips due to under skin blood accumulation. It could be due to angioedema and severe allergic reaction to allergen or sometimes side effects of certain medicine can also cause such symptoms. It could be due to deny Chat Doctor.  I would suggest you to apply lip balm on it. You should take combination of levocetrizine or Ben
