Query: Allergic reaction!

This cream was used on me when I went to the physical therapist for disc degeneration. She rubbed it on my neck, shoulders and upper back. That evening, I realized I'd broken out into hives. They didn't hurt at first but they eventually turned into a rash that had spread all along my arms, neck, chest and back! It itched and I couldn't resist the urge to scratch. Even mild scratching felt like fire underneath my skin. The reaction lasted for a week. The only thing that helped was juicing (drinking a 100% veggie juice I made to kind of cleanse me from within) and rubbing shea butter on it. Now when I go to the physical therapist, I take my own (natural and hypoallergenic) creams. I've never had this kind of reaction to a cream before but I just want to warn anyone who has sensitive skin as well as those who are allergy prone. The therapist said one other person had a bad reaction which made me feel slightly better.
