I Recently Participated In A Labor Day Celebration That Required

I recently participated in a Labor Day celebration that required me to stand and walk for hours. I wore a pair of converse sneakers that cause my right pinky toe to swell beyond belief. The swelling has gone down a tad after resting and soaking my foot in Epsom salt, applying ice and other home remedies. However, my toe has now developed loose skin with what seems to be a pocket of blood beneath it. I am concerned that it may pop and cause further damaged; such as an infection. What procedures should I take to further treatment.
