<s>[INST] Hello!One month ago,i started to have a burning sensation in my throat and my left eye became very itchy..now the burning sensation stopped,left eye is still itchy but my right eye is a bit swollen and feels numb..and also my right upper lip is numb..is this some kind of allergy or something different?i dont understand..i also have slight headaches.. [/INST] Hi,Itching,burning or swollen eyes could be due to allergic or infective(viral mostly)conjunctivitis,keratitis,blepharitis etc.The treatment is mainly symptomatic.The diagnosis can be made by ophthalmoscopic examination by eye specialist.You may require topical instillation of eye drops containing antihistamines and antibiotics (mostly from quinolones group) with some time oral antihistamines and antibiotics.Consult Opthalmologist for further advise. </s>
