Yes there is indeed a dry cough going round and almost flu symptoms. So get some tussin med especially for night-time , drink a lot of water and lemon drinks .and wait it out .Hopefully the cough will ease off if it does not I suggest a doctor visit .
smoking can cause a chesty cough but there is a flu like virus going around wich also can cause it ? Visit your doctor to get him to check your chest out?
