Hellooo.. I'm 15 years old and I woke up with swollen feet and a burning sensation in them... I thought it was odd but went to school that day anyway.. Near the end of 1st period my arms broke out in hives and so i went to a doctor. There was really nothing to exactly treat it, but he gave me Zytec and told me to take it for a couple days. Its the second day of using it and my swollen feet haven't changed, and my hands have actually gotten swollen too, along with my entire body aching like it was the day after a long hard work out session.. I don't know why it would be this way. I'm not using any different shampoos or lotions or anything and I've been eating the same foods. I've never been allergic to any of the medications I've taken before or been allergic to any foods. Can you tell me what you think is going on?
