I was playing basketball and Jammed my thumb really bad with the ball. Didn't think it was a big deal and kept playing on it. Now its 9 days later and the pain is still there, the thumb still look like its been jammed and is still swell up. The 3 day after the jammed, it was hard for me to button my shirt, but now its not so bad, its just the tip of my thumb hurt really bad when I use pressure against it. Otherwise, it doesn't hurt at all. I was wondering if I have a chip bone or with rest it would heal. Cause usually a jammed finger goes away in 3 days, and this one hasn't. Should I get it x-ray or let it heal.

This is the standard treatment for a non-broken finger or toe.

1. Assess the movement in your injured finger or toe. If you can't move it or if it's too painful to move, it may be broken. See a physician.
2. Ice the injury immediately to reduce pain and swelling.
3. Continue to apply ice for 20 minutes of every hour until the pain and swelling begin to subside.
4. Immobilize the finger or toe using a splint or bandage.
5. Limit walking if it causes pain to the toe, and/or wear shoes that don't put pressure on it.
6. Use anti-inflammatory agents such as ibuprofen.
7. Begin using the digit again as soon as pain and swelling subside.

I would suggest having your thumb looked at by a physician as soon as possible to be on the safe side.

If it's a very sharp pain under the nail, you may have a subungual hematoma, or blood or fluid otherwise collecting in the tissue under the nail. When you apply pressure, it causes intense pain on the nerves in the nail bed. This happened to me several times and I know it can be excruciatingly painful. Feels like it's broken, but it probably isn't. Don't use the tip of your finger until it heals or the swelling goes down. This is an aside, and may not be applicable, but when I had a broken finger tip, the pain was very different. Hyper-sensitive to any movement at all, not just pressure.
