I would get to the doctor sooner then later, if it is gallstones with your history of liver disease you dont not want any bile backing up and turning jaundice. I would get to the ER, its almost better for them to see you when you are having an attack so the blood levels will show it...
my skin on my back is very itchy but the research I had done says it's just an attack, I am not yellow and no fever.
I don't think you should wait. I think you should have someone take you to the ER now. With your history of liver disease, the vomiting, dizziness and vision troubles, I think it's very important to get this checked out immediately.
DO NOT DRIVE YOURSELF!!!
I hope you feel better and please let us know what you find out!
