I : I strongly suggest you get seen. Nails are a problem because of the things that can grow on them and then get inserted deep into your foot. In worst case scenarios, it can even cause an infection in your bone! best not to wait on this one. Sorry it's not easier than that.

Yes, see the doc: With it being 2 days since your injury, the fact that there is swelling may indicate that there is still something inside - whether it is part of the nail and/or an infection beginning - it needs to be checked. Make sure you are up to date on your tetanus too. Don't wait to see a foot specialist. What may seem like a benign infection can turn very quickly into something nasty if left unchecked.

Have it evaluated: Deep puncture wounds can be potentially dangerous as one may develop tetanus, or a number of other types of deep infections. If the wound was deep enough they may lead to bone infections. You may need periodic debridement of you wound to remove any unhealthy tissue.
