Hello,
It is my pleasure to answer your query.
I had gone through history and understand your concern.
Your symptoms are may be due to
injury to the ligament/tendon (
Sprain) or injury to muscle(strain) or
fracture of the bones of the wrist.
Cause for the pain and swelling should be evaluated by a thorough physical exam. You might also need an X-ray.
For your symptoms I would have suggested
1.Rest your wrist for at least 48 hours.
2.Ice your wrist to reduce pain and swelling. Do it until the pain is gone.
3.Compress the wrist with a bandage.
4.Elevate your wrist above your heart.
5.Take NSAIDs which will to reduce pain and swelling. They should be used only
on your doctors advise.
6.Make your wrist immobile.
I will suggest you to consult your doctor for identifying the cause for the pain and swelling.
Hope I have answered you questions and doubt.
Thank you.
