<s>[INST] I have a bulge in my abdominal and it is hard I went to my doctor and she said its a hernia, i went to see a surgeon and he said he does not think its a hernia, but wants to do a ct scan, I said if its not a hernia what could it be, he said fat, well the last time I knew fat what not a hard ball [/INST] HI Thanks for posting your query .     Yes you are right fat will not be hard but a localized collection of fat called as Lipoma can be firm ( but not hard ) in consistency .       But neither a hernia will be hard in consistency .      I would like to know more about your abdominal Bulge . Like which part of the abdomen it's there ? Is it painful to touch ? Does the bulge increases on coughing?   Kindly revert back with details asked .       Also to know what is the problem it's advisable to get CT Abdomen Pelvis as advised by your surgeon . Any clarifications feel free to ask , Happy to answer . Regards. </s>
