The swelling in the finger and wrist after an injury is likely to be due to a hematoma
formation due to a soft tissue injury
or a bone injury
. If the swelling is persistent then do get an X-ray done to find out.
The following measures will help you in symptomatic relief:
1. Give enough rest to your wrist. You can use an elastic brace for comfort.
2. Take mild pain killers like acetaminophen
3. Stronger prescription NSAIDS with muscle relaxants may help if simple analgesics do not help.
4. Hot compresses to your wrist will be useful pain relieving measure. You may apply a local analgesic gel on that area.
I hope this information has been both informative and helpful for you.
