Answer:
A swollen finger is a sign of fluid buildup or inflammation of the tissues or joints of the finger. Finger swelling can result from serious infections, inflammation, trauma, and other abnormal processes.
Because a swollen finger can be a sign of a serious infection or inflammation, you should talk with your medical professional about your symptoms. If you experience finger swelling with pain, redness, or warmth, seek prompt medical care.
Treatment :
Apply ice for 15 minutes each hour to bring down the swelling. If you don’t have ice, you can soak the finger in cold water instead.
Keep your finger elevated above chest level.
Take an over-the-counter pain reliever such as ibuprofen (Motrin, Advil) to ease any discomfort.
Hope this helps :)
