Dear Sir/ Madam
Thanks for writing to us.
1. First of all you need to see your doctor or orthopedician to rule out a serious bone or ligament injury
2. If already 24 hours have elapsed, you can try moist heat application on the area. Take hot water in a bucket, add common salt to it and put a towel in it. put this towel on affected area but be careful that it should not be intolerably hot. You can also get a prescription of non-steroidal anti inflammatory drug from your local doctor.
