Right under rib unbearable pain

I am a 28 year old female. I have constant pain on my right, just under my rib cage, sometimes unbearable. I get nauseas, feel like I am starving hungry and as soon as I eat a few bites I feel stuffed. Voltaren injection doesn't even take it away. They have removed my gallbladder(no gallstones)and my appendix(no infection) trying to take away the pain.
I have had a colonoscopy,gastroscopy, laporoscopy, numerous CT scans, and an MRI, I have seen gp's to gynaecologist, to neurologist, to gastologist and everytime they just pass me on to the next person because the don't know. Ive been told I have pancreatitis, Gallbladder infection, IBS and everything else that they can think of, and everytime they look further, it turns out it is not. Its been years, and I cant handle it anymore, it is interfering with my life!! I went for more sonars, and blood test this week, still nothing. Now they want to do another CT scan, but I think they are just grabbing for straws. Is there anyone out there who has a clue, I am at my wits end. they found a 8.22mm haemangioma on my liver, but Dr says it cant be this. (I also keep picking up weight at a rapid amount but don't know if this has anything to do with it, 16kg in 3months no change in diet) I am at my wits end, please can someone help me.
