I am a 21 year old female. I have been experiencing, what can best be described as hot flashes. I will be sitting in a normal temp room in the middle of a Michigan December winter and all of a sudden start sweating. After stepping outside to cool off, I come back inside and a few minutes later it feels like it's 100 degrees again. I ask people around me, "Are you hot?" and they look at me like I'm crazy because they are all bundled up in their sweatshirts. After talking to some girls I know in the medical field, they have suggested that it may be related to a hormone issue. What kind of hormone issue could this be? Is it a hormone issue related to my age? Or something more serious? Is it something that will pass? Thanks for any suggestions!
