Avelox and pain medication

I am a 30 year old female who had taken Avelox several times in the past for sinus infections. However, this time, I had a very scary reaction. About one hour after taking the first dose, I began to have a severe burning sensation on my face, neck, and ears. My skin turned red and looked as if I were sunburned. Within three hours, my whole body was red and burning, but I was shivering terribly. I had a tingling sensation where I felt like pins and needles were being stuck all over my body. I began to vomit and my feet hurt so bad that I couldn't stand to put shoes on or to walk. I also felt very nervous. I went to the ER where I was given an IV with Benadryl and Pepcid for the reaction. I was also given a steroid and pain medication. I had to stay in the ER all night to be monitored.
