What Causes Double Vision,headaches And Tremors In Hands?

of a long question and I plan to see my doctor but I would like to try and isolate my issues if possible. I have multiple symptoms and am not sure if they re related. Often a bachache, my vision has been changing off and on for some time including double vision, I get head aches primarily on my right side including my eye, I have periods of shakey hands for days up to weeks. I often can t remember recent things, names, numbers... and often can t find the word I m looking for. Sometimes I m mostly ok but usually something is going on. There is more but this may be enough. Any ideas?
