I am now able to feed myself again
After last weekend and the awful pain I was rather glad that, by Monday morning I was feeling pretty-much better again. My hands were a bit unresponsive for a couple of days - which made typing a bit of a chore, but otherwise I've been fine.
With no further symptoms, I assume that it was some form of passing virus that I am now rid of.
I am sure that this a relief to everyone.
