I soooo can't do sitting around all day, I seize up to the point of painful to then get my butt of the chair - they are very good at work and used to me walking around and then suddenly playing statues!
Doc gave me some co-codamol to take at work, the dihydrocodeine makes me too ga-ga so I can't take it when I am there!
Another thought, not sure if it will work, is the ibrogel stuff on the butt bit. I say anything is worth a go!
