I would use “bark” for a wound that removed a broad area of epidermis, rather than a “scrape,” which would be a similar injury but that went deeper rather than wider.
A counterpane is a bedspread. Manchester is household linen and cotton items. Towels and pillowcases may be found in the manchester department of big shops here. Presumably because they used to be mass-produced there. IIRC this was a term that I was not familiar with prior to coming to Australia.
I’m getting the feeling that **Qadgop ** thinks I’m a malingerer.
Reading this thread it occurs to me that I would rarely refer to shins unless they had been barked, scraped or whatever. As to counterpanes, yes bedspreads, but to my southerern english thinking, made of cotton, silk etc rather than anything fluffy or wooly.
Only if you took the next two days off work! 
And thanks, AskNott. With the sort of base I can build here, I hope to one day achieve my goal as a syndicated medical confabulist,… I mean columnist!
I’ve only ever heard the verb “bark” used in connection with one’s shin.
I barked my shin yesterday. Lost some skin and got a deep blue bruise. I thought about the use of the word barked in this phrase and considered both the sound I made when I smacked my shin into a hard object and the loss of some skin, like the bark of a tree. I never bark any other part of my body. my neighbor has never heard the term used to describe that accident. I think it is poetic and rich.
I’d never heard that expression before today.
I first heard it on October 3rd 2004.
Jesus, your work environment has made you hard.
(I am a soft Canuck - when we bark our shins or knuckles, it usually means that just the barest amount of skin has come up. That little onionskin epidermis plane…)
I’ve never heard ‘bark’ used to mean an abrasion injury. One may scrape a shin or skin an elbow but bark is new to me.
I’ve heard counterpane to mean bedspread here in the rural South (US). I’ve also heard of people barking shins, knuckles, knees and elbows. Manchester meaning items of domestic linens is something I’m completely unfamiliar with.
