Light headed , blackouts, sweatting, felling hot then followed by cold feelings please help ....?

Answer:
This could be any number of things causing it but without running medical tests on you no one on here can say what is causing it. See your doc and get this checked out.

This could be about a million things - from something simple like electrolyte imbalance to something serious and potentially life threatening. Your best bet would be to go to a medical professional and be evaluated.
