Doctor with troubles losing 1,000 bandages (7)
I believe the answer is:
dresses
'losing 1000 bandages' is the definition.
'dresses' can be an answer for 'bandages' (dresses a wound). I am unsure of the 'losing 1000' bit.
'doctor with troubles' is the wordplay.
'doctor' becomes 'Dr' (abbreviation).
'with' says to put letters next to each other.
'troubles' becomes 'esses' (I can't explain this - if you can you should give a lot more credence to this answer).
'dr'+'esses'='DRESSES'
Can you help me to learn more?
(Other definitions for dresses that I've seen before include "Gets tired" , "Puts clothes on" , "falls into line" , "Costumes" , "lines up as ordered on parade" .)
