Bactrim Fever and Chills, Staph, Abscess, Nausea, Headaches

I was prescribed Sulfa after having a abscess lanced that tested positive for staph. Immediately upon taking the medication I developed a headache...on day 6 of the medication I had had a headache for 6 days and began vomiting violently and soon developed a fever. I immediately stopped taking the medication as advised by a doctor and spiked a fever of 103.4, for the next 36 hours my fever would fluctuate between 100-103.4, accompanied by chills, a feeling that something much more terrible was wrong, little to no appetite, excessive sleep and continued headaches. After blood and liver labs everything came back fine ~ you would think this made me feel better, but it was the opposite...I was terrified that something much worse was going on. I will NEVER again take a medication in this family...what an absolutely horrible feeling. It is currently 48 hours since I've taken a pill and I still am battling nausea....although my fever and chills have subsided.
