Could my pinky toe be bro/ken?

My toe has been killing me forever. I always thought it was the toe next to the pinky toe because it has a bump/callus on the side where it meets the pinky toe. When I put pressure on them it is definitely the pinky toe for sure. It has hurt for a couple years now and I can't think of anything i've done to injure it. It feels like it's broken but it's hard to believe it would linger on this long. When I apply pressure to the top of the toe right under the left side of the nail it pulsates with intense pain. So when I walk on it the other toe pushes down right on that spot. At times it does feel like it is the bone inside but I don't think the bone goes to the very end of the pinky toe that far. Has anybody had anything like this or know if it could be a fracture? It's not an ingrown toenail or anything like that, it feels deeper. Any suggestions?
