I have pain ontop of my big toe. It looks completely normal and I am positive that I do not have an ingrown nail. When I put pressure on it, it hurts.

If indeed you are . Correct there is no ingrown toenail other possibilities could include a subungual exostosis or a bone spur under the toenail, an enchondroma or similiar type of bony lesion. Make sure shoes are proper fit and you werent wearing anyone too tight. An xray would be a good starting point. .
