Note from lot again suffering earache (7)

Ross

I believe the answer is:

otalgia

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

'earache' is the definition.
(I know that earache can be written as otalgia)

'note from lot again suffering' is the wordplay.
I cannot really understand how this works, but
'note' could be 'g' (musical note) and 'g' is present in the answer.
'from' could be 'o' (I've seen this in other clues) and 'o' is found in the answer.
The remaining letters 'talia' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for otalgia that I've seen before include "Problem with ears" , "Ear ache" , "pain!" , "Earache" , "painful condition" .)
