sudden horrible uncontrolable itch in bra area, panty area, and hands. actual swelling in these areas ( whelps are raised and red) hand was left with a soft bump under the skin on my palm. before the itchy whelps I had a bad headache.(I NEVER have headaches ) I took a benadryl and suppressed the urge to scratch as much as possible. It was a 10 on the 1-10 scale. I am a very healthy 62 year old. no sickness, no meds, ever. thanks for your help, jennifer
