Hy, I am suffering from an eye infection. The doctor gave two types of eye drops (Exod, Flurbiprofen eye drops IP). I have been 4 days. It is better at the slow rate. Mean time I am caught with mild dry common cold. I could only feel common cold during running nose. I don t think it is severe but today morning when I tried to clean my throat by artificial coughing I found a yellowish cough with blood. I could feel the taste of blood in my throat. when I was returning to my room I fainted and fall on the floor. I can t see the blood of other peoples especially due to an accident but this time the amount was not sufficient. I am afraid! Yesterday I was feeling a kind of coldness for short periodic time then after that, the situation is normal regarding the coldness. Am I suffering from serious diseases? Help me, please!
