Found some forest trails near my house, so took my son along them this evening. Not a minute after we started down the trail, I stepped on a stick with a thorn sticking straight up. It punctured straight into my right foot along the outer edge, right at the base of the 5th metatarsal where the bone makes a slight bump along the edge of the foot. Well instead of going right home, we kept on going through the woods and through the park. It bled a little bit after I pulled the thorn out, but stopped pretty quickly. After that, though, I noticed some red swelling around the area. I do not believe there are any pieces of the thorn embedded in the skin. It doesn't feel like there's anything foreign in there. I just feel kind of a dull soreness right now if I press on the area. After returning home I cleaned the area with rubbing alcohol, poured some hydrogen peroxide over it, put a bandage with Neosporin ointment on it, and then tried placing a bag of crushed ice around it for awhile while lying on the couch with my foot elevated. Hasn't seemed to help much as there's still some swelling. Is there something I can do to take care of this or will I need to see a doctor?
