HELP!!!!!!!

I'm a 22 year old female with a bit of a weight problem, I brought something like a body shapper and i tried it on and loved it. I wore it all day at work. Later that evening I notice bumps all on my hands and when i looked down i notice many bumps on my legs where the body shapper was on. I have very sensitive skin so I figure the material was not fit for my skin. I return it at the store. took some benedryl and it cleared the next day. At work that day I felt fine, but later that evening I was really cold and started to shiver. When I got off I took my shower and I still felt really cold. I took my temp and it 102.7. I panic and took some tylenol and my fever broke. The next day I felt fine except I notice i was constipated and took something for that. I experienced the worst abdominal pains ever, I threw up several time and was really faint, after the laxitive wore off I was ok, but I still had a fever of 102.2. To make a long story short. I have been dealing with my fever for the last 4 days it only goes up at night to about 102.1-102.8 and after I take mortrin it would break down to 98.8. I have no other symptoms except a mild runny nose and watery eyes. My head hurts a little in the morning and a little of back pains. What could this be? symptoms of the flu?? or a cold?? I feel fine but my temp raises every night! PLEASE HELP! thanks
