Everyday for past several years now, either my left or right eye feels blocked near corners between eye and nose. The pain starts with blockage sensation in this area between nose and ear and proceeds gradually towards back of the eye upto head, at top of the respective eye. Extends towards the shoulder blade region. The pain is every single day and unbearable. No cold or running nose. But when heating pad kept or zandu balm applied near nose and eye region, eyes water out. Continuous white discharge is there. Opthalmologist diagnosed no issue with eye. No issues with thyroid too. Eyes get puffy and red when pain is there. What is the issue, what is the remedy?
