Will this stop me from shipping to boot camp?

I dep'd in November and I ship March. Recently, I developed this brownish/blueish line under my toenail. It runs across on my foot from 1 side to about half way from the other. It's pretty small and somewhat hard to notice. I guess it could be a bruise, but I don't really remember bruising it. If a MEPS doctor saw it, would he not let me ship? Any help is appreciated, and thanks in advance.
