Hi, I Have Been Suffering From This Pain In The

Hi, I have been suffering from this pain in the upper left quadrant of my abdomen. It started over five years ago as a small circular pain that would come and go and the pain wasn't as intense and would go away. I complained to my doctors over the years, but no test or anything was done. Now the area is much larger, the pain much more intense and dose not go away. I went to the ER and the kept me and did a endoscope. They told me that nothing was wrong (GI doctors), and laterally kicked me out the hospital after 1 and 1/2 days. The pain is becoming worse and now is throbbing. I also have no energy. Please help me. What is wrong? Something is going on in my body and I can't get any answers or diagnose.
