Dear all, Thanks for all your suggestions. I was given 18 hours notice to turn up to our hospital for a pacemaker replacement (I wore out the old one - too much late night/early morning programming). Operation successful but I feel as if someone hit my shoulder with a sledgehammer (which they well might have done considering the banging that was going on during the operation). Hope to be back on deck next week to follow up the suggestions.
