It started off in late Nov. as a common-or-garden cold. No problem, cleared up catarrh, dried up cough, and ever since then she has had a silly little dry cough.
She is coughing literally every few seconds, especially if she is not engrossed in something. It is not made worse by exertion, and if she is totally engrossed in something (usu. physical) - and when she is asleep - she hardly coughs at all.
She has had lots of upper resp. tract infections - bronchitis, laryngitis, etc. and is described as "mildly asthmatic" but this cough is not the wheezy asthmatic or barking croupy type cough or chesty that I have seen in her before. She has a nebuliser and at the moment is on Pulmicort and Berodual (don't know if these drugs are used in the UK, we live abroad). Her allergist (who seems to have disappeared off the face of the earth, can't get in touch with her) also prescribed her Ventolin, but for attacks of coughing that leave her breathless, which these are not, so I am not using it.
Atm her GP has put her on a course of antibiotics "just in case it is a bacterial infection", but I can tell she is a bit lost. She wants to see her every few days so she can monitor where the cough is going but she is the sort who will listen if we put forward our own theories so wondered if any paed/allergist types have any ideas what we could suggest. She says she can't hear anything in her chest...
This is not (I hope) serious but it is really tiring us all out, and poor DD most of all. Any ideas anyone? Could this possibly be a nervous cough, and if so, what to do? She is not in a new setting, there is no tension at home (except around getting out of the house on time in the mornings ), teacher says she is happy and popular at preschool. We are stumped.
