I know some people with CFS get fevers at night on a frequent basis. Others never get fever at all. I never had a fever for the last 5 years, even in the depths of terrible flu that would last up to 6 weeks. Last week I got a cold/flu like infection and had a fever of 38 for 2 days, that would not subside. What do you think about this? Do you think this is a good sign? I wondered if my immune system was suddenly working again in ways it had been unable to do for ages. (Those who know me from other threads may know I have been on huge antibiotic therapy for about 6 months to treat several bacterial infections) I'd like to know how many people get frequent fevers without an acute infection, and how many never get fevers no matter what they have.
