Hi, I have had this pain along my while right side of my abdomen for almost a year now. It is like a stabbing aching pain. The pain starts about an inch above my umbilicus and about 2 to 3 inches to the right and radiates up sometimes all the way to my right breast bone. If I am laying in my left side or standing up, I can feel almost a sausage shape lump on my right side where the pain seems to originate above and to the right of my umbilicus. It does not bulge as a normal hernia would but It is hard and and sometimes when I put deep pressure on it, i feel like it pushes back into somewhere right under my right rib. I ve been to 3 doctors and none of them ever seem to take enough time to feel it and they don t push deep enough. They say it is trapped gas or muscular pain. I had a CT scan and a HIDA scan last year when this all began and they were negative. I have been researching and to me it sounds like a spigelian hernia. Is it possible the CT scan missed this since this lump goes away when I lay on my back? If I can get them to send me for another CT, or an MRI is it possible to lay on my left side during the scan since I can only feel the lump when lying on my left side and when standing? I d appreciate any input you might have. I am desperate for answers and no one has been able to help me and I am getting really depressed about having to deal with this pain just about everyday now. Thank you
