Abdominal Bloating and Upper abdominal pain

I've had this problem before and it lasted for 8 months.  It did not feel like gas at all.  I even went to U of M Hospital to a specialist to see what the problem could be.  They told me it was trapped gas.  It didn't even hurt like gas, just bloated and very uncomfortable.  I did a colon cleanse and it did get better but it took 2 months.  Now I have bloating again with upper abdominal pain and I don't have much of an appetite.  I just had a scope (EDG) and a CT Scan.  I do not know the results of the CT Scan yet but the EDG didn't show anything.  I look like I'm 5 or 6 months pregnant.  I'm 51 and have Hypothyroidism, Diabetes, GERD, Asthma, CAD. I've had a total hysterectomy.  I'm really tired of getting this and no one seems to know what is causing it.  I feel miserable.  Does anyone else have any idea what this could be?
