Still can't do much riding so decided to change my attitude. A cursory (read 'study intently') look at the OS map showed up some trails I had never ridden.
Rode through some gorgeous villages with appealing pubs and then hit a bridleway. What a gem it turned out to be ... eventually! Turned into a singletrack descent with largish loose stones, bit of a gully, then a fallen branch that had to be moved. Was getting a bit carried away then realised that if (when) I wiped out, nobody would ever find me. 
Checked out a few more trails, enjoyed the sunshine together with a Winter picnic.
Exploring rocks. 
How was your day?
Any further developments/diagnosis?
But how good is it to be out in the countryside when the sun is shining?
