I have a pain that starts on by back, far right, just below my shoulder blade; after a day or so, the pain starbursts across my back in all directions; another 24 hours or so, it starbursts through my core up into my chest and worse, thru my stomach causing extremely painful stomach spasms. This may last a week or 3 months. As of late, my stools are released with a yellow liquid rather than a clear liquid. My pee is clear.
