Open Question: I was recently diagnosed with a staph infection (skin type) and have been on Bactrum DS x’s a week.?

Now I, in my spine moderate pain, low fever, headache, not to mention just beginning to feel a bit too. I started with the bird flu three weeks ago, and then Staphylococcus aureus is now back pain .. could cause this? I also have chronic kidney and bladder problems, but back pain is not a kidney. Any answers would be useful. Documents and visited three times a dermatologist too … next stop the emergency room, right? ?
