hi, thank-you for providing the brief history of you. A thorough clinical Musculoskeletal assessment is advised along with an x-ray or CT scan. As the injury is on the ribs and three fingers away from the xiphpoid process a thorough understanding of the rib bone and muscles is required. Also lungs had to be checked for any damage since there is discomfort in the chest. Taking a therapeutic ultrasound therapy will help reduce the inflammation and pain. Also, using the taping technique the rib movements can be restricted and the pain can be lowered Followed by the healing , proper costal breathing exercise technique is applied to make sure the Strength in the muscle groups. Usually in my clinical practice patients respond to Therapeutic ultrasound therapy, taping and costal breathing exercises. Regards Jay Indravadan Patel
