Please help with my visual disturbance and tingling.

Hi doctor,

I caught Lyme disease two months ago. I had a 7 hour long vomiting session with it. Since then, I have had tingling in my arms, legs, hands and feet. A month ago, I started having kaleidoscope vision, followed by a medium headache. This is now happening three or more times a week and lasts for about 20 minutes. It starts as a small circle or a line, like a cut diamond first and then it goes colored, which expands until it takes most of the vision. I cannot really see anything at this point. I feel as if the esophagus is blocked when I swallow food. I have never had migraines in my life. My mother has multiple sclerosis (MS). What could cause these visual disturbances and tingling? I am on Sulfasalazine, Melperon, Leflunomide, Pantoprazole, Thyronajod, Vitamin D, B12 and Shilajit. I have Chiari malformation of about 12.78 mm at last measure, psoriatic arthritis, lupus, gluten sensitivity, herniated cervical disc, fibromyalgia, bone cysts and spurs, restless leg syndrome, wrist degeneration and cartilage too.
