After being stung, has anyone's neck still feel swollen even days after the sting?
I can't really answer your question because I've never been stung on the neck. Do you have swelling of the neck when you are stung elsewhere on the body? If so, that might -- might-- be cause for concern. I think we all react a little differently to bee stings. Let's see what others say.
Welcome to Beemasters, by the way. Feel free to ask questions. There's a lot of knowledge on this website and you'll find a lot of generous, helpful people ready to offer advice -- maybe several opposing opinions on any topic, but all sincere.
