just wondering????

last few days i have been suffering from virus which is now being treated with antibiotics. This virus kills my appetite and leaves me feeling fatigued. At night i go to bed with various layers on as i am literally shaking with cold and yet my skin can be warm to touch. The shakes come from inside. Yet i wake in morning soaking with sweat , I was wondering if anyone with medical knowledge maybe able to tell me if my body is going to burn energy excessively at this point. ?
