@bhavit I was looking up Hypereosinophilic Syndrome which seems to be like an overreaction to things the body would be allergic to, so that begs the question, what was in the IV just prior to the episode where your daughter lost feeling in her arm? Was it a steroid treatment for the Hypereosinophilic Syndrome which essentially should calm down a reaction or something else? I would be looking to find out all the ingredients in that IV and wondering if that was the cause of the reaction. It doesn't hurt to ask the question.
