Hello, I read about your problem. There are couple of possibilities Firstly it could conjunctivitis ( red eye) - in which case using antibiotic drops, artificial tears, frequently washing the eyes is what i would suggest. Second possibility is you could be having a stye - so look is there is any lumpy swelling in your upper or lower eyelid- if this is the case then hot fomentation , oral antibiotics, analgesics along with antibiotic eyedrops is what i would recommend to relieve your symptoms Another possibility is that you could be having an acute attack of angle closure glaucoma where the space between transparent layer cornea and iris is narrowed and suddenly raises the eye pressure. this would need proper evaluation and immediate treatment at eye care centre as it is an emergency. Please feel free to ask any another questions that you may have
