Thanks for asking at Healthcare Magic. 
I read your question and I understand your concern. Commonly 
Gall bladder has three types of problems. 
1. Stones in gall bladder:
there is pain in Right upper quadrant,  nausea
2. Inflammation of gall bladder
pain right upper quadrant, fever  with rigor and chills, vomiting, malabsorption
3. Malignancy of gall bladder. 
palpable mass in right upper quadrant sometimes 
obstruction of bile duct with yellow discoloration of sclera and white stool because of lack of 
bilirubin. 
I would like to advise to you to have an 
ultrasound abdomen to ruled out 
gallbladder problem. if the ultrasound was normal then it's gastric problem
most common of which is 
dyspepsia. 
Hope it helps best.
