Right side pain

I got some kind of intestinal virus with diarrhea back in July.  Immediately after I started having a pain in my right side just beneath my rib cage.  Since then the pain has greatly increased and spreads around to upper right back.  I also tend to have sharp pains in my right front side of and on throughout the day.  Around the same time as this pain showed up I also started having significant joint pain in my left wrist which has not subsided.  I cannot gain weight no matter what I eat and I do not have diarrhea or vomiting even though every once in a while I feel a little nauseous.  I also am having extreme fatigue.  I have had ultrasound, HIDA scan, ct-scan and all showed my gall bladder normal.  The ct-scan showed my liver was oddly shaped with an extending left lower lobe and that my gallbladder was folded but the doctors tell me this is normal.  All my blood work is normal except a positive ana which my rheumatologist says has such low titers that she can't diagnose me with lupus or anything.  I also had a positive smooth muscle test for autoimmune hepatitis but the hepatologist says that these titers are also too low to diagnose that and all my liver function tests were normal.  I also have a laporascopy picture from 6 years ago that shows a strange light colored membrane covering my liver.  The doc just said it was "interesting" but showed no concern about it.  Could all these doctors be wrong and I really do have a problem with my liver?  Should I ask to have my gallbladder rechecked (it's been about 8 weeks since my last tests)?  The next test recommende to me by the hepatologist was a differential nerve block.  Should I go ahead with this and is it extensive or painful?  Will it even help or just raise more unnecessary red flags?  Any suggestions or advice would be greatly appreciated.  I have been going through this for 3 months now and am at my wits end.  I just want to feel and be healthy again.  Thanks.
