Mickey, suffering with a hurt related to joint pain (11)

I believe the answer is:

rheumaticky

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

'related to joint pain' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'mickey suffering with a hurt' is the wordplay.
'suffering with' indicates an anagram.
'a'+'hurt'='ahurt'
'mickey' anagrammed with 'ahurt' gives 'RHEUMATICKY'.

Can you help me to learn more?

(Another definition for rheumaticky that I've seen is " With inflammation in the joints".)

I've seen this clue in The Independent.
