I believe that gallbladder pain is usually on the right side, generally in the back of the rib cage - but not always.

Sounds as though Fumih is allergic to something in her tom yam.

I used to get an upset stomach when I took my vitamins on an empty stomach. The B vitamins seemed especially bad. Now that I take them AFTER a meal, I don't have the same problem. I try to spread them out through the day so my tum isn't overwhelmed.

Try eating very simpley for a couple of days to see if things settle down, then add back a new food every day to see if the upset comes back.

If you are taking any meds or aspirin or ibuprofen (Advil, Motrin) they can cause stomach irritaion. Take them with food if possible to protect the stomach lining.

Remember, I'm not a medical person and your doctor is your best source of advice.
