I’m sorry that you’re having a bad time with this condition, I know from experience how hard it can be to get through this, although our health problem is not exactly the same, the symptoms are very similar. I always had a lot to coughing and that really wore me out because it took so much energy away from me, combined with shortness of breath with breathing difficulties. Every time it flared up I would go on antibiotics for treatment, however I read that we can build up an immunity to them just like any other medicine and eventually I don’t think that they were very effective for me. I now prefer to rely on inhalers for healing, they help open up my airways and also help to strengthen the lungs. I think that it would be helpful to speak with the doctor about changing your medication and see what works best for you, antibiotics have and still are often over prescribed, this is not to say that they don’t offer any benefit but it could be possible that your system is perhaps getting immune to them.
