Pain under right rib cage

I developed this pain about 2 years ago and generally I cannot feel it, but it acts up when my stomach gets upset and tends to produce air rather than digest (have low stomach acid).

When my stomach gets bloated it presses against whatever it is on the right side and it causes the discomfort.

Been checked out and no gallbladder stones or anything else unusual was found. Liver function tests were doen twice and they were normal also.

Could this be a parasite issue or more of a liver cleanse issue? Or both?
