Is pain burn more calories from human body?

Do you burn more calories when you are sick?

In my case it seems so. I have a very strict eating and workout habit. I only eat carbs and cheat on Saturdays. I also cheat on Holidays, Birthdays and when I am sick.I have been ill since a couple of days which also means I could not do workouts and was lying in bed all day long. I got high fever and am still freezing all the time. During those days I ate some really bad stuff like lots of potato chips and never bothered with salads, fruits or greens as I just dont want to move or spend alot of time filling my stomach.However this night I went to the toilet and risked a short glance and posing in front of the mirror and man did I look jacked. My shoulders were so defined and 3D (ok light is very good too haha). But still, for feeling like a wet towell I looked surprisingly ripped.Two things might have led to this. First I had much more sleep and maybe less stress which led to less cortisol and better fatburn. Second I was still not going overboard with calories and my glycogen depleted muscles soaked all the water in with the carbs making them fuller and looking dry.I read that injuries lead to more burnt calories. I think some diseases do that aswell.
