What Causes Cold Sweats Along With Dizziness And Headache?

The other day, while standing, waiting on my husband, all of a sudden I started to burn up, broke out in a cold sweat, light headed and had a splitting headache, I started to feel some better after a while even though I still felt weak, I laid down, just feeling weak is all at this point, but all of a sudden my heart felt like it was going to beat out of my chest, husband took blood pressure, it wasn t really up but my heart rate was like 107. Curious as to what it could have been.
