oops-a-daisy

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

'said to help after a fall' is the definition.
I can't tell whether this defines the answer.

'in retirement some days i 'ad a spoonful' is the wordplay.
'in retirement' shows that the letters should be reversed in order (retire can mean to go back or backwards).
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'ysiadaspoo' is hidden within 'days i ad a spoonful'.
'ysiadaspoo' in reverse letter order is 'OOPS-A-DAISY'.

'it's' acts as a link.

Can you help me to learn more?
