I am very allergic girl. Allergies can trigger any foreign smell. It is manifested distributed as allergic rhinitis. That is, it turns out that I reside infection in the nose or what? On such a virus for the first time I hear, and I was horrified to some extent. Especially the fact that the body temperature rises so high. This can actually cause fever. Of course, if there are any symptoms, you should call the doctor, because the consequences are very scare me. It is necessary to immediately treat a runny nose, and after a long illness to raise the immune system.
