Wound Infection?

2 days ago on my way back home, I fell and wounded 2 of my fingers and the base of my palm. Unfortunately I didnt have any antibiotic or disinfectant, so I just washed my hand, however, today when I took a look, one of my fingers were swollen around the wounded area. I immediately went out to get some disinfectant, and after washing my hand, I applied it on. It is not really any warmer than other parts of my body, and I didnt see any red streaks coming from the wound. I had a slight pain in my temple (the muscle), but that may be result of eating (I eat quite a large amount).I'm not sure if this is somethign serious or not. I'd like to know the best course of action please.
