Please, do not let this scare you, because not being a health professional, I can easily be wrong, but it sounds like symptoms of a stroke. However, as I just said, I am not a doctor. So to be safe than sorry, please see your doctor. There is still time to catch this and take care of it. Please keep us posted on updates.
This could also be side effects of a bad migraine. Numbness in face one side, vision impairment, ect. See a doctor and get your brain checked. MRI or MRA as soon as possible. There are treatments if it is migraine problems. If it is a stroke or TIA you should be treated ASAP!
