Thanks for writing in.
Our primary aim in your case is to exclude underlying fracture
. As there is severe pain
along with swelling there is high chance of having an underlying fracture especially at your wrist mainly Cole's fracture or fracture both bone of lower part of your forearm.
So its very urgent to have a x-ray evaluation of your right hand both AP and Lateral and it will be wise to have a x-ray of your knee joint also. If any fracture is there then consult an orthopedic surgeon immediately and take his consultation and operative intervention may also be needed if there is fracture both bone of your forearm.
In the meanwhile you may apply ice pack locally along with analgesic
gel for symptomatic relief. You can take non-steroidal anti-inflammatory drugs for pain relief along with pantoprazole
