TS, is your stomach feel like tension? Feeling is like when you shout or sing?

I have that for quite sometimes. Suspect stress related also.

Stomach bloating, then did endoscope, colonoscopy, ultrasound for gallbladder, blood & urine test.

I losing weight since that. Been 2 years almost 10kg gone.

Don't know what else to check?

Have to let go and take it easy!
