I Sustained A Fall From About 5ft Up In The

I sustained a fall from about 5ft up in the air and hit my foot on the ground. I originally thought it was only bruised however I did feel some intense stiffness after the injury occurred. Fast forward to 3 weeks later and I’m still feeling pain when I move it. I can bear weight on it, but when I move my foot side to side or up and down I feel pain on the top of my foot, just below the bump on my ankle. I’m wondering wether or not it’s just bruised or if it sounds more serious than what I oroginally thought
