aching/pain

[PinkLady]

Consider these lines:




"If I can ease one life the aching,
Or cool one pain
...
I shall not live in vain"



Does 'aching' mean the same as 'pain'? (Or is it softer than pain?)



And does 'ease' mean the same as 'cool'?

Thank you.

aching can be the same as pain

In this context ease means relieve or make better
