Good day, I have such a question. For two days now, my one side of the face has been hurting. I got a cold (flu) not long ago ? A brown discharge comes out of my nose, I don't understand, I feel terrible ???? My head also hurts badly. We are in a village here, there is no doctor. Only on Monday will we go to the hospital. Please tell me and please what should I do? ?
