pressure right side

Hi
I have been having pressure in my right side right under the ribs especially after eating for years. I never had real pain or attacks. I had a echo done to see if I had any gal stones but they found none. The only time I feel smooth in my right side is right after I drink my fresh apple juice on empty stomach in the morning. I have been on a organic vegetariona diet for many years. I tried one flush mixing half a cup of olive oil with half a cup of grapefruit juice and nothing came out (cant get the epson salt in the country where I live). Was the flush not strong enoug? Should I try more? Or may be stones are not my problem?
