I spent several days working on my scooter. I don't have a work bench so everything is done with me bent over and squatting for hours. And now I'm sore from head to foot. Last year I went through something similar while changing tires in my wife's boat trailer. When I was done I couldn't unbend and stand. I had to scuttle across the driveway to a stone wall and use it to help me to stand up. I'm 64.5 years old so age might explain everything . But could PD explain it also?
I'm wondering if a chiropractor might help.
