Yup ... gettin old sucks...Yesterday I took a nap around 3pm. When I got up, I discovered I couldn't walk, Pretty sure I twisted and pinched a nerve in my lower back, near my right cheek. Could hardly sleep last night, but today is better.......
Been there had the same similar problem. Mine was the sacroiliac nerve.
Right side for me to.
First time was stepping off the porch and felt like I'd dislocated my hip.
Usually as long as I do my stretches I'm good.
