Since 2019  i started having zigzag /flickering  lines in vision. It occurs for around 15-20 minutes ( more in my right eye and little less in my left eye) After this stops i get a headache . In the last 2 instances I did Anulom Vilom Pranayam when these visual disturbance were occuring and i got comparatively less headache then what i used to get. Previously this happened once a month but in this month it has happened weekly. What should i do next ? Should I get my eye checked? Or should I visit a neurologist ? Also I would like to mention here that back in 2019 when this started I also had numbness in my right lips and fingers along with zigzag lines in vision I consulted a neurologist who suggested a MRI which came normal.
