Hi ! Your history suggests that you might have torn some muscle fibres and might have developed a hematoma
(collection of blood) in the are which you think is for appendix
. This will give rise to the pain while coughing and sneezing
. You may take some anti inflammatory tabtets for the pain and swelling which will gradullay subside. See your doctor if the swelling increases. However, one should not be very much confident of this diagnosis and appendicitis
should be kept at the back of one's mind as a coincidental pathology. If the pain gets worse, you should see a general surgeron, who may advise you for an ultrasound
abdomen apart from some routine blood tests. Wish you an early recovery.
