For months now I have had what I thought were hives. I get them everywhere on my body at any given time of the day. It doesn t matter where I m at or what I m doing. But now they aren t just welps they are actual knots. And they are very painful and itchy. They make my hands swell, they get in my head and the knots feel like I m growing horns. I can t figure out what it is. But I don t feel like its an allergic reaction.
