Hello. Not a weird question at all
During a flare, you joints may become inflammed, which causes your skin to feel like it is on fire. Because of that, the thinking is that we must have a really high fever...when the thermometer actually shows our temp as normal.
Also, lupus patients can run a very low-grade fever, but it feels like (on the inside of us) that we must be getting ready to keel over with a stroke because we're sure our temp is probably way high....but it's not.
Not a weird question at all, just a side effect of Lupus.
Hope this helps.
