I had the strangest thing happen to me tonight. My girlfriend came up to go to yoga with me. She picked me up and we went. When we got there I noticed I was sorta itchy on my arms. I had noticed some itching on my legs earlier in the day. As I lay in savasana for our first meditation, my entire being started itching. Violently. My head, my neck, my arms. It was horrible. I made it through to begin sun salutations and it was just unbearable. I went into the bathroom and noticed hives on my face and arms. I went outside and my instructor was pretty concerned. After a few minutes I thought it was getting better so I went back in but in the first pose I just became overwhelmed. I had these hives all over me. I told my girlfriend I'd have The Husband come and pick me up and I left. I walked about a half mile down the street... it was amazing. I've never had an experience like this. The welts started to dissipate and by the time The Husband got there they were pretty much gone except for tiny remnants of them but I am still itchy all over. I have no idea what caused this.
