What Causes Left-sided Headache Along With Dull Eyesight In The Left Eye?
Need not worry about your eyes. They could still be contributory.
Detailed Answer:
Thanks for asking on HealthcareMagic.
I have gone carefully through your query and understand your concerns. It is apparent that the cellular composition of the retina (the ration of rods and cones, and their concentration) is different in the two eyes of yours. Since the ominous stuff like macular degeneration, retinal detachment, papilledema etc. have been ruled out there is less to worry about. Nevertheless, this is possibly enough to strain your eyes and that could lead to a headache like the one you are describing.
I understand that you have already tried all possible treatments. I would recommend you to try acupuncture. Studies have proven the benefits of acupunture in migraine and chances are that you too could benefit from it. Give it a try.
I will also insist you to try relaxation techniques.
Let me know if I could help further.
