what are the difference on usages between 'suffer' and 'suffer from'?
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.
