What Causes Fatigue And Hot Flashes?

I am 75 yrs old and have had a heart attack 4 yrs ago. I have been having extreme fatigue since Sunday. I have gotten chilled twice but mostly very hot. I don t know if it is fever or not but I get so hot and then sweat profusely. I sweat a lot normally but this is more. I wake up at night wet. Last night my joints/muscles ached all night. I seem to fell better and then late afternoon feel bad.

Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.

Being hot and chilled and then get to sweat, lead us to think about Infection. It is hard to detect the cause especially without a history of medications or any other symptoms. But I'm sure to say it looks to be far away from being a cardiac cause. Possible conditions are hidden fever for some infection in your body or thyroid disorder. You may need to visit your doctor and most probably he/she will do some lab for you like ESR, CBC to check for any infection and thyroid function tests to check its state.

Wish you a good health!
