According to the Cambridge Advanced Learner’s Dictionary, ‘suffer’ means to experience physical or mental pain.

(i)Mary’s pelvis suffered some damage from my first baby 1 year ago.
(ii)She's been suffering from cancer for two years.

aren't that both (i) and (ii) talking about physical pain? then why do (i) use 'suffered' and (ii) use 'suffering from'?

i am so confused.

thanks for answering.

There are subtle differences, sometimes invisible for many.
suffer from is continous (over some period of time) and means suffer because of something
suffer something means undergo in reference to certain moments in time, =suffer it

I suffer from a flu.
I suffer a heart attack.
Can you see this slight difference?
