I am 43 years old, and I haven’t had my period for over 3 months. I am on thyroid medication for the last 12 years and my doctor has reduced my medication but it did not help. My pelvic ultrasound results are good. I can’t sleep properly and I also have severe pain in my knees. Is this due to the medication? Is there anything I can do to help my body? How about home therapies? Thanks.
