I am a 43 yr old female. I have been post menopause since 2006. I have experience an increasing problem ove the last two yrs of fatigue, muscle pain and weakness, joint pain (sever at times), brain fog, weight gain and just a general hard time functioning on most days without pushing hard to do so. I ve been diagnosed with vitamin D deficiency and arthritis. Thyroid has come back negative, although it is tender to the touch. Any help is appreciated.
