‘I have been in worse problems’ is this statement gramitically and syntactically correct? I have tried searching in Google and also on quora But I got both positive and negative answers
What strikes me as wrong (or at least not natural) in this sentence is "in problems". One has problems, but isn't usually in them.
I have been in worse situations.
I have encountered worse problems.
