hmmm wondering if maybe this is a herx reaction? I was also concerned this may be a toxcity symptom, but when searching on the net i found it relates to Fibro and MS and even just anxiety. Still don't know what to make of it. It seems most people have had it recently, has anyone had it for a while?
Personally, I get it everywhere- quick little twinges of "icy hot" feeling if that can even describe it. Also get it on my head which really freaked me out the first time I felt it.
