I'm 51 and haven't had a period in 10 months. My feet feel stiff, especially in the am. My legs feel like they have lead weights, pain in the buttocks that shoot down my hamstrings. Arthritic feelings in fingers. Exhausted all the time, can't stay after work. I have some hot flashes, not a major issue. Sleep is pretty good. Major weight gain, 23 pound in last 6 months. Use to work out, too exhausted now. Recent blood work, Low Vitamin D (17%) on weekly pill (just took 7 pill) Also, low protein levels, low blood pressure. Extremely stressed due to personal family situations. I am supposed to go back to internist who I have only gone to once, very nice but a quick five minute visit. Not sure who to go to get help, the constant pain and weight gain is extremely upsetting. I was thinking of an endocrinologist, but not sure. Never reached out like this before, but found Dr. Friedman's videos very informative. looking for any suggestions?
