Left eye is paining
Doctor Answers (1) on Left eye is paining
I suppose that there is no irritation, itching, discharge etc... meaning No infection
Is it a lid swelling which is only one sided?
Is your eye otherwise normal apart from working hours?
Is it the lid or conjunctiva which appears red?
Does the swelling increase when you bend your head to toe level within few minutes?
One of the cause could be hemangioma which should be observed if the symptoms are not increasing; else it should be excised or electrocoagulated if its increasing.
You need to be examined by an ophthalmologist to come to a clear cut diagnosis
Hope this helps :)
