I had several mosquito bites on my arms (discovered Sunday morning). I usually have an allergic reaction to mosquito bites where the bites swell to an enormous size, but this is the first time that I've experienced pain. The pain felt like the aches you get when you have a fever but about 10x more painful. It lasted all day. At night, I took a hot bath, then rested in bed with a heating pad on my left arm and took an ibuprofen. In the morning, my arm didn't hurt anymore.
I have an appointment with an allergist to get this checked out. It seems that my reactions are getting worse.
