me too. Combination of getting a yorker on the toe, lost the nail with a new one growing back under and then got another ball on the toe which screwed up the regrowing nail. That culminated in a recurring ingrowing nail problem – very painful – and finally having a lateral excision to take the outer 2/3 of the nail and nail bed away which solved it.
Although if you check a recent thread on strange biking related injuries, it's not been entirely incident free since.
My advice would be if you look after it as it regrows, it should be fine but if it does start to ingrow go and get it sorted – well worth the effort.
And don't use half moon shaped clippers / scissors to do your toenails. Cut them straight, allowing the corners to protude a little. The chiropodist told me that was a no-no.
