Hello,
Your symptoms are indicative of visual
migraine (ocular). You are suggested to get clinically examined by an Ophthalmologist, 'cause untreated visual migraine may cause temporary
vision loss, flashing of lights, blind spots with nausea &
vomiting. Avoid stress & anxiety at all cost. If diabetic, control your blood glucose levels. Maintain your weight & make sure your blood pressure is within normal limits.
Take meals in time, cut on addictions if any. Know the factors that trigger headache (migraine) & avoid them. Stay well hydrated.
Numbness in the fingers may be due to developing
peripheral neuropathy. Get nerve conduction tests & biopsy, if required Imaging tests done. In the meantime, take food rich in vitamin B6, B12 or supplements.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Nupur K, General & Family Physician
