Kate,
I have also dealt with these irritating hot/cold flashes and have about gone mad. At first it was the menopause flashes, but they finally subsided. Now, I just get these intrusive flashes. I have at times gotten so hot that my makeup slides right off the face, my hair becomes weight and stringing sticky. I don't have them as much as I have since my disability has come thru. Now they progressively got worse and it started to become wonderfully better Ok, ok, so I had some help. I was started in July on long term oxygen and that has helped tremendously. Not saying everyone needs O2 to feel better, but it has helped my sweats.
In the meantime, I will still continue to have those basic hot/cold flashes that drive my husband crazy and in an onry but mean way.
Nancy
