Painful knot under right rib cage

I was wondering if any of you have had this?  I've had a painful lump under my right rib cage for months now.  The pain radiates rfrom front to back.  My docor felt the lump also and sent me for a ct scan.  It didn't show anything.  I don't know what to do next.  I've had my gallbladder out so its not that.  Anyboby ever have this?

 

Try not to worry. I know it's easy for me to say. Your Dr. Did right to oder a Ct scan. When having a lump on our body that is abnormal, so I am glad you showed it to your Dr. Please let us know what comes out of it. I pray it's nothing and you can have peace about it.
