Lower right rib cage pain, numbness. It?

I had a pregnancy last year, post 4 weeks I started experiencing lower rib cage or just below the rib cage pain, if I sleep on the right side. Had a miscarriage in 16-17th week(last week of March 2017). The pain vanished after that for almost 5 months, it started again since October. Visited at least half a dozen different speciality doctors nobody knows what it is, all of them saying may be some ribs abnormality or its nothing, but I know it's not nothing, cause the pain is frequent now. Sometimes I feel the numbness with pain, the skin over it doesn't feel same as left side, feels kind of numb if I scratch for example. Nothing came in full abdomen sonogram. Pain starts mostly after having food and if I hunch or slouch while sitting. Today it's hurting like anything, nothing is working, walking, sitting, sleeping on either side or on back.Right now in my 6th week of pregnancy. Can anyone diagnose it? Please help!
