Talk to General Physician on Feeling Episodes Of Weak Vision In One Eye And Upset Stomach For 4 Years

I feel weak vision in my right eye suddenly. When i feel close 1 eye and compare with other i feel weak vision. It has happened before but got ok and now its happening again. I dont know the reason of this And i have been dealing with upset stomach and cant focus on driving easily and feel imbalance while i stand. I got my all tests done m.
