Suggest Remedy To Stop Itching And Sweating Due To Menopause

i have had night sweats and hot flashes for the past 12 years, so I guess I am one of those women who will suffer the symptoms of menopause forever. I have learned to live with the embarrassment and discomfort, but now twice now, I have developed a bad rash and terrible itching that lasts for weeks. I imagine that it comes on from trapped sweat but the itching is driving me mad. I can't take hormones because of family history. What can I do to stop the cycle of sweating and itching?
