Ball of foot pain

About 2 months ago I stepped on a rock with bare feet. Then did it again about a week and a half ago and then 3 days ago I was laying in the bed and moved my comforter with my foot and heard a loud pop. I was in intense pain like made me nauseous type of pain. I can kinda walk on it more like hobble but the pain is still pretty bad especially when attempting to walk. It doesn’t hurt so much when I’m not on it. Is it possible that I could have fractured it or maybe something else.
