Sounds like some kind of infection could be due to blockage. You need to see an optometrist or ophthalmologist to get antibiotics. You do not need to let an infection go untreated.
Hi
Welcome to the MedHelp forum!
Either it is an allergic reaction to something or it is an infection. Clean the eyes with cotton swabs dipped in water and throwing the swabs in a closed dustbin. Use one swab for each eye. Wash hands well after each eye wash. Wash your clothes, bed linen daily separately from others. Other than this, it can even be glaucoma. Needless to say, consult an eye specialist immediately. Take care!
