Thank you… he takes B12 supplement drops, and magnesium is in the sleep supplement he is takes. He also had a complete blood panel taken the last week of September, when I took him to the ER. We told them what was going on, and they checked for everything possible. We’re still researching natural treatments for severe digestive issues. His Gastric doctor, that did the upper GI endoscopy and colonoscopy, hasn’t bothered to call us back since the tests he took a week & a half ago….we talked to him before the tests about Covid affecting Gut/ Brain signals, the system and he said well before we look at that we need to do these tests first. Now he hasn’t even called to go over the results! Which we’ve had in email, since last week! It’s very frustrating!
