That's sounds very nasty Sarge.

A daft question if I may?

You have said that you are on pain killers for ailments various in the past and I did read somewhere that certain types, especially the opioids, can cause or exaggerate said complaint so I'm wondering if this could be the cause in your case?

Whether yea or nay I do hope you recover swiftly.

I will be away from this Friday in North Norfolk for a week so will be silent myself.

My very best to you Sarge and, again, hopefully a quick recovery.
