PG, I've had allergic reactions like that before and no one could figure out what the cause was. I was itching so bad that I was bruising myself from scratching and I was covered head to toe with hives, its no fun. I was hoping that you were getting some relief from the patches since you hadn't posted anything negative about them. Do what you can to get it under control even if you have to take benedryl. Try some moist heat or ice for the ON. I know its not the greatest, but it may get you a little relief I'm sending low pain wishes your way. Take good care, EE
