Anyone else with a low bodytemperature feeling feverish in a normal body temperature range?
I would say many, if not most of us.
Is there an explenation to it?
The low body temperature could be due to low thyroid; you should have this checked out if you haven't already. But even with proper thyroid levels, our body temperatures tend to be low. Temperature regulation does not seem to work properly in a lot of us. This function is a job of the hypothalamus, which has numerous problems in ME/CFS; for example, it is deeply involved in dysautonomia, as it controls the sympathetic nervous system.
As for why you feel feverish when your temperature goes up by the amounts you describe, it's the same reason that people with a higher normal temperature feel feverish when their temperature rises by a similar amount. The immune system has detected either infection or inflammation, and cytokines are released. One of the effects of cytokines is to make you feel sick (in this case feverish), so that you slow down your activities and the body can use all its energy to fight a perceived threat.
