I believe the answer is:

lumbago

I'm a little stuck... Click here to teach me more about this clue!

'backache' is the definition.
(I know that lumbago is a type of backache)

I don't understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for lumbago that I've seen before include "Painful condition" , "Back problem" , "Gaul mob (anag.)" , "Back complaint" , "Pain -- a bum log (anag)" .)

I've seen this clue in The Telegraph.
