I have alot of joint and muscle pain and have used ice packs without any problems for
years. If I use the ice pack now, I get very red, hot, itcy hives
and they last awhile. Also, it was raining around 40 degrees and I brush the rain off car door and within a few minutes my palms of my hands had the same reaction. I do have asthma and allergies to pets, pollen, tree nuts, & seafood.
