Can sle lupus affect body temperature regulation? ex: hot then 10 min later cold etc.

Possible, not common: SLE is a great masquarader to cause a variety of different symptoms in different people, including regulation of body temperature if parts of brain controlling temp is affected. A thorough evaluation and monitoring of your disease by a rheumatologist is warranted. Feel better:)

Lupus: Highly unlikely but possible. Lupus sometimes can affect the thermoregulatory areas of your brain but this would generally occur in the context of other symptoms.
