Sinusitis
"I took Bactrim DS after the first antibiotic didn&#039;t work on my sinus infection. I started to feel better after 4 days, however I developed joint pain in my hands and knees. I have arthritis from an autoimmune disease, but it&#039;s usually controlled very well by a maintenance medicine. On day 8 I noted lots of swollen glands in my neck and a slight temp. After I took my antibiotic that night my fever shot up to 103, I was shaking, teeth chattering, with severe joint/muscle pain, my face looked sunburned, and my body was red/blotchy. I stopped the Bactrim, but the fever lasted 2-3 days, the arthritis was severe for about a week and I still have fatigue. Good news is ENT did recheck and infection is gone."
