My 4.5 year old son has a chesty cough and runny nose for approx 1 week now.  Hes not coughing anything up at all and I have been using his ventolin 4 hourly and some benadryl chesty cough with nasal congestion to help the cough and dry up the nose.  Tonight I noticed he was twitching  his arms.  I asked him if he was doing it on purpose to which he responded he wasnt he was just cold.  He also says he is not finding it hard to breath (there doesnt appear to be any major sucking in at his ribs) he just wants to stop coughing.  Any ideas on what I should do would be appreciated.
Hi, Kindly give some steam inhalation to relieve nasal block. And get him evaluated as it's more than a week of coldDisclaimer"This provisional advice provided by me stands subject to the patient undergoing a physical examination and is based entirely on inputs provided by patient/attendants.
