Partically detached toenail pain.

This past Friday night, I tripped and stubbed my toe on the heat register. Yesterday, I took OTC for pain relief, and kept it wrapped with neosporin to avoid dirt. (I bartend and drive beer cart at a golf course so I am on my feet basically my whole shift 6 days a week.) And of course, I've banged it on 2 chairs since Friday night. Today, I tried to let the wound get some fresh air, but when I got home, I noticed what looked like clear puss coming out of the wound & I am now in extreme pain. Medication hasn't helped me pain wise. I used Hydro P. And made sure to clean it up when I got home. The toe nail now looks like it is about 1/3 of the way off down at the nail bed. Is there anything else that can help soothe my pain? Should I let it fall off naturally?
