Oh right, sorry, completely wrong end of the stick. Assumed he was much younger! Sound he's had a very tough life, and must have been hard on you. Hope you get good news following the colonoscopy.
I've rung the doctors today anyway, as I've had chronic spinal/back pain for almost 6 months now. The pain is in the same spot, so I'm concerned I've got some spinal degeneration or athritis. I do have a bad habit of sleeping on the sofa 4/5 nights a week because the kids still like coming into our main bed, so dunno if I've caused myself damage.
