Unexplainable debilitating pain

My grandfather has severe pain, lower back pain.
He has been to  3 doctors, had a CT scan 10/10 and a Bone Scan 9/10 both were found negative. Here  is what he described to me.  
Low Back Pain- Above the hip bone below the rib cage started as a fist size feeling in the right kidney area (kidney removed May 09')(cancerous tumors).  Area now affected is 2 to 3 times as large and has additionally reached around the front toward the belly button.  
Sensations are Heat/Tender skin touch/constant pain to the point of tears. Resulting in not being able to sit/walk/stand/lie on my right side/back/stomach.  Driving or riding in a car over bumps is extremely uncomfortable.


This is from a man that hiked major mountains has always been healthy and is not a complainer.
