Little lumps (7)
I believe the answer is:
nodules
'little lumps' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for nodules that I've seen before include "Small lumps - led us on (anag)" , "Small rounded lumps" , "Small swellings" , "Loudens due to small lumps" , "Loudens like lumps" .)
