I got the shots (temples, forehead, back of the neck and shoulders) on Sept 3rd-Friday. Tuesday morning my arms were itching like crazy... and then my chest. I had to force myself to stop itching because it started burning. After about an hour it went away but I've noticed that my head, neck and even stomach itch a lot too. Thursday morning 9-9-10 I was awakened because it felt like my entire body was burning/itching at 3am. I'm still itchy. Is this common? Should I be concerned?
