vertigo

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

'dizzy spell' is the definition.
The answer and definition can be both states of affairs as well as being singular nouns.
Perhaps you can see an association between them that I don't see?

'i got worried following very short' is the wordplay.
'worried' indicates anagramming the letters.
'following' is a charade indicator (letters next to each other).
'short' means to remove the last letter.
'very' with its last letter removed is 'ver'.
'i'+'got'='igot'
'igot' is an anagram of 'tigo'.
'tigo' after 'ver' is 'VERTIGO'.

Can you help me to learn more?

(Other definitions for vertigo that I've seen before include "Dizzy feeling when at great height" , "Dizzy sensation brought on by heights" , "Trouble with heights" , "attack at altitude?" , "the Eiffel Tower effect" .)
