Dizzy/cold sweats

The past few days or so, about 2-3 times a day, I start to get a hot flash with cold sweats and get very light headed (see sparkles) and nauseous for a few minutes and it goes away. This happens very randomly, whether I’m doing something or just sitting. Don’t want to be an annoying patient that calls her doctor about every little symptom so was wondering if anyone on here has had the same thing and what their doctor told them?
