<s>[INST] I have a round bump about the size of a grapefruit on the right sidev of my belly button. I can push it in and it makes a weird sound. I also get like a nausus feeling when I do so. I have had a complete hysterectomy and I also have had Colin surgery due to diverticulitis. What could this be? [/INST] I welcome you to health care magicI am Dr Fahim, General Surgeon and I will be addressing your health concern                 I have gone through your question and understood your concerns. With available information to me it appears to be a ventral/incisional hernia because of the previous history of abdominal operations along with nauseating feeling when you push it back. It hints towards presence of bowels in it. Although hernia is a clinical diagnosis, but nevertheless, Ultrasound abdomen will conform this diagnosis. Incisional hernia can complicate into intestinal obstruction which is then emergency and patient will need urgent surgery. Incisional hernia’s treatment is operation called hernioplasty e prolene mesh repair under spinal anaesthesia. Wishing you all the best and rapid recovery.I hope my answer will help you. Do rate my answer if you like it.Regards </s>
