I am looking to find out what the persistent pain is in my left rear flank? It used to be an intermittent pain, but now it does not let up. It is up near the back of the lower 3 ribs. I often feel like there is a tight belt being drawn tight under my chest under the ribcage. I asked my Endo about my adrenals and without doing any checking was told, there is nothing wrong with my adrenal function. Historically, I have already had two major adrenal crashes since I became Ill in 2005. Is it possible to be inflammatory bowel disease, kidney stones or a liver problem? I have been taking about $400 per month of Rx palliative medications and Rx supplements since 2005 and am faithful with my 13mm CPAP nightly. The pain is like a tightness, dull in nature until I move. It gets worse when I eat even a small amount. I have not been on any pain meds.
