Does crypto cause stomach issues?

For the past few days my stomach hurts/burns like it does when I'm on antibiotics. At first I thought it was something I ate. But maybe it's something I drank?! I'm on crypto plus which has a few things in it.

Crypto doesn't usually cause stomach issues, but what you're taking has Juglans Nigra which can cause havoc on the stomach and the duodenum. It's good stuff, but kills a lot.

You know, I am not sure if it's the meds after all. My stomach hurts so bad, it woke me up really early this morning. Zzzzzzzzz... Just burning. I am thinking maybe gastritis? I took some Pepcid but no relief so far. TMI but my stools have been looser than normal too. Is it the herbs? Or is it a Lyme flare? Or a herx? Or h. pylori? Or a stomach bug I picked up? Ah, the good ol' is this Lyme or something else game.
