Did you by chance start any new meds around the same time this started happening? Not all meds cause an instant reaction..they build slowly over time. For example.. the first time my son was on amoxicillan he had no reaction. The second time.. a rash on his back. The third time..full blown hives. So if you started a new med even before the symptoms started..it could be related. Just a thought. hope you get feeling better my cankle comrad!
