Hi John,
I can fully comprehend your plight having undergone this one myself. In my case the surgeon lost most of the "sludge" resulting in several months of fighting infection and further surgical procedures to drain it off! I'm glad your surgeon was a good one, not that I'm complaining about mine, these things happen.
In any case I wish you well and good luck with your move to the Cornish coast. You'll not be far from me on the Devon coast (Torbay)

Kind Regards,

Dave.
