Just everything it seems, my pain varies from chronic, acute and intermittent. Recently I tripped in the backyard carrying my 16 lb dog (watered the grass earlier and it dark and my dog ran off). Now my left foot hurts, my hands, the bottoms of both feet, and both knees hurt a little bit. When I sit and type at work my lower back starts hurting after 1.5-2 hours. Intermittently I have TMJ pain. Chronically I have Right knee pain after sitting awhile and walking actually helps. I’m not good at being inactive and have been walking less the past few days since fell 2 days ago.
