Hi ! Good evening. i am Dr Shareef answering your query. This could be because of a hematoma due to muscle strain and minor tears while doing rope swinging. In that case if confirmed by an ultrasound, you could go for an anti inflammatory drug for a few days. If clinically it is difficult to distinguish between an appendicitis and a hematoma, then it is much safer to get the appendix removed than to leave a diseased appendix inside the abdomen. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your health problems. Wishing you an early recovery. Dr Shareef.
