Since I started this new job, I sit in a chair for 12 hours, no place to really walk to, or move around. My body has gotten so out of shape. i don't do much at home since I am so tired when I get there. So now I am wondering if my body aches because I don't do anything, or if I did go swimming or walking if it would increase the pain. Don't feel any relief when I wake up, just as sore as when I lay down. Afraid to do anything because i am in so much pain now...what will happen if I DO exersize. What do you all think?
