I looked up my abd US & it says (small break in the fascial plane suggesting a small hernia at the site with minimal omental fat herniation) serious??

Talk with your doc.. Refer this Q to your doctor since the marginal findings of US have to always correlate with clinical profile so to make a reasonable, not perfect, judgement since no test bears a 100% of accuracy and specificity. Besides, all life events always display on their pattern of full spectrum; therefore, it is hard to make a perfect diagnosis especially at their early almost non-discernable stage.
