I have a bulge / mass that appears left of my abdomen I'd say slightly above my belly button to the left. 

This seems to appear after a meal around 1 hours after, and settles after a few hours 3+ hours. It is mainly seen and felt when lay down flat or when lay down but torso sat up slightly.

The lump is probably five cm in length and four in width. It isn't painful when it is there and I can push the lump without pain but it just stays there when I remove my hands from pushing it, its not solid but it's not soft it's kind of little the end of your nose in the sense of hard/soft.

after reading various articles and comments online some have suggested it's due to weight being a slim person it would be because of that however I disagree, I've always been the size that I am. Never have I had this before

any suggestions on what this could be? 

Also I have had a scan to rule out a hernia although my doctor has requested a more in depth one to double check I highly doubt it is as it doesn't appear with significant coughing as I have a bad cough at the minute and it's not affected it. 

 

Thank yoy
