I've been taking Effexor XR for a while now, and I have these bumps on my calves and shins that are bright red in color, and they are almost hard like a mosquito bite would be. They don't itch, nor do they hurt, they range in size from about the size of a dime to about the size of a half dollar. They don't bother me other than they look awful. I also have tons of purple small bumps on top of my right foot, again they don't bother me, these feel identical to a mosquito bite. Anyone else have this problem? I can't find anything that looks similar. HELLLPPPPP!!!
