question: Hi! I am 34, female and have been experiencing a burning sensation or hot flash in my left forearm that spreads over my hole arm. This comes in waves and has been happening for about a month now. Since about the 28th of December I have been experiencing dizzy spells. In the last two to three days, I seem to be getting slurred speech while I m having a dizzy spell. It last about 10 to 30 seconds at a time.
