Heat Flashes, Cold sweats; 24 yo female hormonal inbalances?

I am a 24 yo female, been expiriencing heat flashes and cold sweats for about 2 years. It started in 2010, towards the end of the year, Through out the day I will expirience a heat flash, sort of like a flow of cold/hot sweat. I get clammy and red. It's very annoying, I'm always hot. I have regular periods, not taking any meds, and currently not having any stressful situations. I also work out and live a pretty healthy life. Ive read abt hormonal inbalances, do you have any tips or answers for me. It's rly driving me crazy! I work at a doctors office as a medical assistant, and it happens all day, patients tend to ask all day of I'm okay. It's rly bugging me. Please help! Thanksss
