In the optician's today for new glasses.
As part of the consultation I was asked about illnesses etc and of course mentioned the fibro. Turned out that it could cause problems with my sight but OK for now.
However the optician was quite knowledgeable, turned out a patient earlier today had fibro and was a Doctor!
Pity there's such a thing as patient confidentiality cos I'd have loved a long chat, might have been interesting to hear from someone on both sides of the tracks?
