You have a bruise (contusion). There is swelling and some bleeding under the skin, but no broken bones. This injury generally takes a few days to a few weeks to heal. During that time, the bruise will typically change in color from reddish, to purplish-blue, to greenish-yellow, then to yellowish-brown.
A finger bruise may be treated with a splint or buddy tape (taping the injured finger to the one next to it for support). Minor bruises likely will need no other treatment.
Home care
-
Elevate the hand to reduce pain and swelling. As much as you can, sit or lie down with the hand raised about the level of your heart. This is most important during the first 48 hours.
-
Ice the finger to help reduce pain and swelling. Wrap a cold source (ice pack or ice cubes in a plastic bag) in a thin towel. Apply to the bruised finger for 20 minutes every 1 to 2 hours the first day. Continue this 3 or 4 times a day until the pain and swelling go away.
-
If buddy tape was applied and it becomes wet or dirty, change it. You may replace it with paper, plastic, or cloth tape. Before taping, put a thin strip of cotton or gauze between the fingers to absorb sweat. This will help prevent any breakdown of skin or fungal infections.
-
Unless another medicine was prescribed, you can take acetaminophen, ibuprofen, or naproxen to control pain. Talk with your doctor before taking these medicines if you have chronic liver or kidney disease or ever had a stomach ulcer or gastrointestinal bleeding.
Follow up
Follow up with your doctor as advised. Call if you are not improving within 1 to 2 weeks.

Contact your doctor right away if:
