Hi
I have been woken up in the night by my left arm aching and have to get up to take pain killers. It is an ache type pain either usually in the in upper arm or forearm. I also seem to have red lumps/blotches appear around my body. So far had a few on my waist, then one on my shoulder, one on my back that seem to come and go but don't hurt. My palms of hands can be also super itchy and again this morn were a bit red at the base of hand. Any ideas what it is? should I be worried?
