Thanks all for your very kind comments. Bottom line is that my Primary Hyperparathyroidism symptoms continue to rage on with renewed vigour now that the effects of analgesia and sedative meds from the operation have completely worn off. I've had one of my worst few days ever with this disease this week, but we've all been here before, and the symptoms will ebb and flow as usual over the coming days and weeks. All I can do now is try to look forwards to having another go - possibly in a couple of months or so, complications permitting - and I'm now starting to be able to get my head around that revised reality.
The good news for all waiting for surgery though is that the wound does not bother me in the slightest. Given that in essence I had a HPT op apart from the actual removal of the gland, this hopefully will be of some comfort to others. I had minimal pain relief following the op (2 x 1g IV paracetamol, 50mg oral diclofenac and finally 1 g oral paracetamol during the first 20 hours post op). I've needed no other pain relief since then, and I'm now 6 days post op. I have good neck movement - provided I'm sensible, though coughing is still somewhat tender. Otherwise, no issues!
As for having the op under local anaesthesia, I can't say it's the best experience I ever had - far from it, but in some aspects I have had worse days out at the dentist.......! I'm not sure I'd elect to do it again unless circumstances dictated no alternative, but if anyone out there is currently queued for a local, there's nothing really to worry about as far as the procedure itself is concerned.
