I will only ask this...is the pain right below the left side on the rib cage....kinda like you took a tennis ball and squeezed the heck out of it?
If yes? Then, it’s the same thing I’ve had for fifteen years. And early on, with no diagnosis (and still none)...I learned to raise my arms above my head and twist to the left with the whole body. The shooting pain disappears within ten seconds, and doesn’t come back for at least a day or two. Lately, with a different nutritional diet...I haven’t had the pain in six months (less fat, more salad oil, more fruit).
It is right below the rib cage on the left side. It is mostly dull like what I had with my gall bladder, but will then seemingly out of the blue feel like I’m being stabbed over and over. Then go back to dull.
