Thanks,
@13 rider but I've fallen at the second hurdle! Woke up with terrible chest pains in the middle of the night of 15th February. Straight to health centre the next morning. Diagnosis: pneumonia had returned in a severe fashion. I'll cut a long and grisly story short: three weeks in hospital, the first half in Northampton General, the second half in Glenfield Hospital, Leicester. Good fun being transported up the M1 in an ambulance. Three chest drains fitted and a two hour operation to scrape all the infection out of my chest. Discharged exactly one week ago. Stitches out yesterday at my local health centre by the same nurse who first diagnosed me a month earlier.
No cycling before I can walk - in the sense that I've to take two walks a day trying to get mildly breathless on each one. Respiratory physiotherapists' orders. This should fully inflate my right lung.
No sympathy sought - I have in fact been superbly treated by the NHS. And collected not only a full EU set of professionals who looked after me but almost a full UN set. The best tick being the morning I was seen by a Peruvian doctor accompanied by a Malawian nurse.
And much inspired for the rest of 2018 by the contribution earlier in this thread by someone who commented to the effect that you can only do what you can do. Good luck to you all.
And if I've learned some advice to pass on, it would be: Don't Catch Pneumonia!
