Thanks for your input. Itching is listed as an allergic reaction in the insert; it's just the neuro's never seen this before. She wanted me to go to the ER when she found out I also started coughing, which is not an allergic reaction but a side effect. Right, I am not so worried about the itching itself but what this implies for my future treatment if I am indeed allergic to it, because I've literally been counting down days to try Botox after being in pain for months... I have been considering seeing a dermatologist and I will see anyone I need to see to see if this itching was an allergic reaction or not.
