I am a 27 yr old female. For at least the past year. I've been having hot flashes usually everyday sometimes my face and ears get so hot they tingle. I also get random feelings of being light headed that can usually be associated with nasuea. Also, probably unrelated my hands shake sometimes. For example, I was trying to feed my daughter one day and it took almost all of my concentration to hold the spoon steady for her. What could this be symptoms of?
