I have had a constant 99 degree temperature for about four weeks, which started when I had was being treated for a staph infection that wouldn t go away. The staph sores have gone away, but I have been feeling extreme fatigue, body aches, loss of appetite, heart palpitations, swelling of my left foot and leg, and diarrhea. I also have the feeling as if my the lymph nodes in my neck are very swollen, but they don t feel or appear to be. It makes my throat feel tight. My lymph nodes were swollen when I first had staph appear.
