on the 15th march 2011 i started to feel unwell, a week later i went to my GP with wheezing, chesty cough etc,to i have been asthmatic for 35 years, he gave me 10 days antibiotics and 10 days steriods, which i have had plenty of times before and it has done the trick, after the course was finished i was as bad as ever so went back and the course was repeated for a week, now 6 weeks later i have a hacking cough, am bringing up green and almost brown phlegm, and sound as though i smoke 40 a day although i have never smoked, have tried without success today to get ANOTHER GPs appointment as there were none available, as a widowed mum to 13 year old twin boys, i am now beginning to get anxious as to why i am still not right, work colleagues and clients, i work as a homecarer to the elderely are commenting daily on my cough, as its so bad, what could it be, i have not as yet had a chest xray done, but am becoming increasingly concerned, your advice please would be very much appreciated, kind regards
