Hello, I Have Several Things Going On. I Was Recently

Hello,
I have several things going on. I was recently prescribed monovision contacts (right - near, left - far) and my brain just can't seem to adapt. When I first put them in both the near and far vision were spot on. After several days the right eye started seeing double and my right face became numb from my cheek to my upper lip. When I take them out the numbness subsides however when I put then back in it seems to come back. A complicating factor is that I was diagnosed with and started treatment for MS which can have some of the same symptoms. What kind of doctor would I see to get this resolved? Is it related to sinus pressure or is something going on with the MS with respect to my vision? A VER test indicated I have a small delay in my brain interpreting vision stimuli so I am wondering if this may be related to the numbness.
