Toe Joint Question?????????

Ok so today I was running around with the boys I nanny and ended up running into a wall, which hurt really bad. My 2nd toe got the blunt cause it is longer then the rest and now there is some pain. I can still walk on it but again there is some pain. The biggest thing im worried about is that in my second toe (2nd joint from the top) when pushed to the left gives me a popping feeling in the joint. What is going on??? Any help would be awesome!
