Gall Bladder problems

I am not sure if I am posting this in the right area so please excuse me this is my first time here. I am trying to get some information I have been dealing with right upper quad pain and nausea for over 3 months now it is worse when I eat so I have lost 23 lbs. to avoid the pain and nausea. I had a hida scan done with a cck injection the ejection fraction was only 48% which my dr says is abnormall but not enough he wants to repeat it in 4-6 weeks but my problem is he doesnt think it will be any worse by then so why do it? Is there anything else I can do to help the pain and nausea since I really dont think surgery will be an option anytime soon. Also the cck injection gave me terrible pains and nausea. Thanks for all the help
