I Believe I Am Having A Gall Bladder Problem. When

I believe I am having a gall bladder problem. When I eat fried food or food containing lots of cheese, I get a lot of discomfort around my mid-section and feel very full. Twice now I have thrown up from fried food or cheesy pizza and each time I find a whitish-capsule shaped, soft object in my vomit. The most recent time all I ate prior to tossing it was a banana - found 3 "capsules" - broke one open and found it was more white inside and looked smooth
