Hi, my son has a swollen Penis from a bug bite. This has happened about 1-2yrs ago. We have given him Benadryl early this AM and again in the early afternoon and not seeing any results (the previous time it went down quickly with 1-2doses). We have given him a dose of Claritin. I'm not seeing any changes and it has possibly gotten bigger. Or it could be he's sleeping and his blood is flowing. Either way if the swelling does not sub side how soon should I take him to the doc?
