I wasn't quite sure where the sentence should end or what the broader context was, but If you want to emphasise that this cocky character is in denial of feeling pain as a result of hurting his leg, this translation might be a good way to put that message across by focusing on the 'pain' rather than the 'injury' aspect of 'hurt my leg', this is why I would propose the 'fájlalnám' rather than 'megsérültem/megsértettem volna' translation, whereas the 'or anything' part emphasises his evasiveness about the whole thing, so this is why I felt it was good to also include the subordinate clause 'vagy ilyesmi' at the end.
