Same here re lurgy sufferers -- boss is being lovely at me doing not full days and doing what I can. I feel fucking awful tho. SO bored of this. Wish it was bacterial as a good dose of something antibioticky would be MAGIC! Viruses are POO. Why can't we nuke them properly too?!
Regarding your hand, you're not usually a wimp so I would assume it is still painful cos you b0rked it good and proper and your body is trying to heal itself which takes TIME! (Patience being a hard trait to have in recovery). Hands are complex as fuck, hospitals are thinking of creating a combined orthopaedics + plastics hand specialism. The difference between a HAND specialist and general orthopod is amazingly different! My friend who had a plated break (after a week of immobilisation) but simpler sounding than yours was off work 8 weeks cos he was just WIPED as well as being in pain. He kept trying to fill/empty this dishwasher cos he lived in a madhouse and no one else would do it, he had to be stomped on by his clinicians to STOP and actually rest properly!
I have pretty badass pain thresholds (altho not as much as in childhood) and my simpler carpal tunnel + tenosynovectomy surgery in 2009 had a recovery from 23rd Dec well into Feb... I deferred my return to work by a further 10 days on Occ Health doctor advice until I was virtually pain free. I was recommended 6-8 weeks, I had nearer 10. There were some things I could do straight away, typing being one of them (for short periods) and other things I could not do at all for weeks.
TL:DR - you're not a wuss, healing injuries hurt!
