British surgeon's finding skin problems (8)
I believe the answer is:
blisters
'skin problems' is the definition.
(blister is a type of skin problem)
'british surgeon's' is the wordplay.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'surgeon's' becomes 'Lister's' (Joseph Lister, father of modern surgery).
'b'+'listers'='BLISTERS'
'finding' is the link.
(Other definitions for blisters that I've seen before include "Bubbles of water on the skin" , "Air bubbles in a coat of paint" , "Swellings filled with air or fluid" .)
