menopause treatment

:? Hi, Im a 50 yr old woman. Im going through menopause or pre-menopause. Im just beginning to miss periods. At first, I thought the hot flashes and night sweats weren't that bad. However, now Im beginning to get them constant through out the day. I excercise, 30 min cardio four times a week. Im 5'3 128lbs I eat well. I had a hip replacement 3yrs ago, I do take up to 4-6 altram and 3 soma's daily for spasm. Is it possible that my medication is causing my symtoms to increase?
