Thank you for the information,
I would advise to get an examination.
You need an X ray to rule out a fracture there when there is swelling with restriction of movement.
Please keep it at rest & elevated.
You can apply ice for the first 48- 72 hours.
This should not be applied directly.
Pl apply after wrapping it in a towel for 10-15 min., leaving in between for the temperature to return to normal.
You can try anti-inflammatory analgesics like ibuprofen, naproxen if you do not have any contraindication.
You need to take it after meal to avoid irritation of stomach.
I would advise to get an examination by doctor.
I hope this information helps.
I will be happy to assist, if you need any clarification.
Please feel free for any follow up query.
