Hi, Thanks for using HCM.
Extreme swelling and had X-ray normal suggest severe sprain
. Crutches and bandage are the main line of management with complete rest. Pain will be there till complete healing and this is normal process. Give rest to the movements as the injured tissue requires time to reunion or heal. If repeated movements that will injure again. Take NSAID
. Follow your doctor advise. Hope I answered your question.
Feel free to ask me if you have any further queries.
Wish you good health. Take care.
