Thank you for the query.
All your symptoms can be caused by anxiety
indeed. Due to stress and anxiety, bowels can get stimulated to work with increased frequency. This can give abdominal pain
, urge to pass stools, nausea, gas problem
. Headache behind left eye radiating to the forehead can be caused by nerve irritation
due to an inflammation, spine problem. It can be also anxiety related.
Stools problem can be also caused by chronic bowels infection. That is why I suggest you to have stool tests and stool culture test done. Discuss with your doctor Rifaximine treatment. You should also start Magnesium
400 mg supplementation. Avoid coffee and other caffeine containing drinks.
Hope this will help.
