No, all the Doctor did at the time was diagnose post nasal drip but my partner did not suffer from such frequent colds at the time. He had the ongoing cough which he seems to suffer every Autumn. He also had a bad cold last Spring, again in November then February this year and now.
Thanks for your help. He has a balanced diet with plenty of fruit and vegetables. He doesn't drink or smoke. I will suggest your comments on getting it investigated, and we'll also try your other suggestions too.
