Big toe pain/tender when i press on the nail, need help!?

Toe Pain: Several possibilities come to mind. The easiest approach would be to see your podiatrist for a thorough evaluation, foot xrays and focused reccs. It is possible that you have a nail injury or some lesion beneath the nail causing your discomfort. Even a bonespur on the phalanx beneath the nail is possible. Check out the apma or acfas websites for information about board certified docs.

Few possibilities: Cold be an ingrown toenail, by pressing on the center you may be driving the nail into the corners. You may have a "subungual exostosis" this is a bone spur which grows under the nail, you could have a subungual hematoma - but that would be obvious to you as that is blood accumulation under the toenail and you would see it. This is usually simple for a podiatrist to diagnose and treat.
