Thanks for posting your query.
It takes awhile for a bruised bone to heal..weeks to heel.
Sprained fingers are extremely common in ball sports such as basketball or netball and frequently occur due to a specific incident such as a hyperextension force (backward bending of the finger) or a sideways force.
Knuckle swelling may occur when blood or lymphatic vessels are obstructed due to severe injury
or infection. In the presence of extreme trauma, the vessels are damaged directly, or the swelling of surrounding tissues impedes circulation.
Most patients with a sprained finger make a good recovery with appropriate physiotherapy
. One of the key components of treatment is that the patient rests sufficiently from ANY activity that increases their pain until they are symptom free.
Protective brace is often required for a period of time to stabilize the joint and protect it from further damage.
Treatment of a finger sprain in the first 48 – 72 hours is vital to reduce bleeding, swelling and inflammation. This should involve following the R.I.C.E regime which comprises of rest from aggravating activities, regular icing, the use of a compression bandage and elevation of the affected limb.
Anti-inflammatory medication may also be useful in this initial phase of injury and can hasten the healing process by reducing the pain and swelling associated with inflammation.
Hope I have answered your query.
Wishing you good health.
