Another suggestion is to have your neurologist evaluate your migraines, do a small fiber neuropathy skin punch biopsy to check nerve damage that affects skin sensations causing itching/burning/temperature issues. They should also consider a MRI of brain to rule out anything causing migraines and vision issues. My son was told by his neurologist to take magnesium and omega 3 supplements which have helped reduce his migraines with aura. The minute he gets aura, he needs to take Motrin or Tylenol before pain hits to prevent painful migraines that cause him to vomit. This helps prevent the worsening of his migraines when they start. Drinking a lot of water with electrolytes also helps him with POTS blood pressure drops. He has a heart defect and gets light headed when he stands up plus Reynauds blood vessel spasming. We use the LMNT electrolytes brand and it is good. You need to drink at least 50% of your body weight in ounces of water with electrolytes to ensure proper hydration. This helps with headaches and blood pressure.
