I got a bee sting, I think, and one of my testicles yesterday about 2 p.m. Later on yesterday, they swelled up a lot, and there is lot of pain.  My doc told me to do Benadryl for 24 hours, but to call him if that didn't do it.  I've been doing ice too.  there are large blister looking things on my penis, and I am worried.
Hello, It's the effect of bee string, which persists for several days. therefore, do not worry about the blister. Apply ice. Use loose undergarments. Take painkeller and Benadryl. They will help to reduce pain and swelling, although it takes time. Do not worry. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr. Sujoy Dasgupta
