Gallbladder symptoms? Please help

iv been having what i think is gallbladder issues for around 3 years now , firstly just started with very bad nausea and fatigue , then one morning i had a very bad pain in upper abdomen with vomiting and sweating. ever since the episode i have been left with pretty much constant upper abdomen pain mostly to the right with right shoulder blade pain also. i still have the bad nausea and it gets worse when i eat, i get reflux, bloating heavyness , pain in right side of chest and a constant discomfort in stomach. i also get the feeling of faintness and being very exhusted but not all the time . when it first started i had a ultra sound, endoscopy, xray and internal xray. they came back clear so i later had a ct scan which also came back clear. About a week after is when i had my first pain attack so the hospital gave me a hida scan which had come back borderline abnormal at 32% . i am now booked to have me gb removed. The problem i am having is i do not perticually have more pain after food, i definatly get more nauseous after food but the pain doesnt perticualy get worse as its always there . does anyone else have this , is it definatly gallbladder , without massive amount of pain when eating ?

I’m surprised all your scans came back clear?
The ultrasound I had showed stones straight away, then I had an MRI for a more detailed look. Only then was I told i needed my gallbladder out.
