I have a large swollen bump on my toe to the right of the nail. It is painful. How do I fix it?

Get it checked. Without a description it's hard to diagnose. Could be ingrown nail or many other things. Either give better description or see podiatrist.
Foot pain. Pain is not normal. If you feel it's lingering even if no swelling nor bruising, pain is your indication you need to see a doctor. I'd recommend asking about possible contusion to the location foot. You may need an xray to rule out other pathology. I hope this helps.
