Hey. I copied your topic to Foot Disorders, where you may get some more answers

You should be fine. Keep the area clean and dry. Apply a non-stick bandage (no cotton balls, I've learned that from expereince - ow!) to the area if you feel you need extra protection from your socks, along with Neosporin to kill bacteria. Rinse gently with water when you shower. Don't leave it submerged for long periods of time in water. Wear sandals if you can to keep fresh air around the wound and promote healing.

As for paintball... I would suggest staying off your toe for a week at least, and not doing anything rough where you might stub it.
