I'm in my late 40s & in the beginnings of menopause with hot flushes etc and I'm getting really stiff. If I stand up, having been sitting for a while, it takes me some moments to be able to stand fully straight. I feel it all over my body, like my insides have turned to quick-setting concrete! It even hurts & takes some moments/minutes to be able to fully stand on my feet without them hurting. Has anyone else had this? What did you do about it?
