Women with a low body weight, are frequently under high stress, or in perimenopause tend to have irregular periods. These women have very low estrogen production, so the body has trouble communicating to the ovaries that eggs need to be released, and ovulation does not take place.
Often starting during perimenopause, it may suddenly become painful to get out of bed, walk upright to the bathroom or get dressed. Quite often the joints of the back, fingers, knees and ankles are afffected. I was on Zoladex for 6 months with hrt 7 years ago. Following this I had sore hips for about 18 months after.
