Are Episodes Of Hit Flashes, Dizziness And Stomach Discomfort While I Get Anxious About Falling Ill Something Serious?

hi, so when I think of being sick, i tend to get a sudden and deliberate hot flash that last a couple of minutes. This also tends to give me a weird feeling in my stomache, kind of like it just gives up all of a sudden. I also get really dizzy and my head starts to throb.
