Pinky Weight Gain My Toe Hurts And I Didn't Injure It. What Could Be The Problem?

My toe hurts and I didn't injure it. What could be the problem? - pinky weight gain

I have worn no shoes at about 1 / 2 per week, not because I leave the house. It is not too tight shoes. It hurts to bend it, but I can not bend me. I heel on a chair or something. I tried to open it, because it feels swollen and cracked. It is near my little finger. The two opposing toes feel really bad. What is the cause? I have not grown or anything, so do not think that it is. Suggestions?
