Please if somebody can help - vocal cords problem since flew to japan and got laryngitis bad?

Viral or physical: The term vocal fold (chord) problem is very non-specific. If you are hoarse from a long flight, there are at least 3 possibilities. You may have talked too much (voice abuse), you may have contacted a viral infection from another passenger (laryngitis) or the physical environment may cause dryness of the throat and larynx. Time and fluids or occasionally oral steroids will resolve your problem.
