I can empathize and hope you're better very soon. BTW, the beautiful photo with your message is included in Andrew Swales' 2022 calendar, which is now for sale on his website. I've ordered one.
I had travel booked for December - Christmas dinner in an HF Holidays country house hotel in Derbyshire, along with a short "Discovery Tour" of the area, then Holmfirth in Autumn of 2022. But I developed a different pain from the usual assortment, which was eventually diagnosed as a torn muscle. The only fix is surgery, which is scheduled for early March, followed by 6 weeks of no weight on the operated leg, a few weeks of recovering enough strength in that leg to climb stairs with a cane, then more therapy. Total recovery is 18 months, to ensure that the tiny wire spiral is firmly seated and holding the tear together. At age 77 now, I have no idea whether or not I'll be able to travel at all by then.
