I noticed come congestion in my chest.  When I lay down at night I hear a whistling, wheezing sound in my chest.  I went to a doctor he checked and  I was told to take an over the counter Claritin for two weeks (I did).  He felt it was allergies.  Im still having the same problem and it has continued for about 2 months.  Im a 54 yoa male.
Thanks for your question on Chat Doctor. I can understand your concern. By your history and description, possibility of bronchitis is more likely. Bronchitis is inflammation of airways. It causes bronchospasm and this in turn causes chest congestion, wheezing (whistling sound) in chest. So better to consult pulmonologist and get done clinical examination of respiratory system and PFT (Pulmonary Function Test).PFT will not only diagnose bronchitis, but it will also tell you about severity of the disease and treatment is based on severity only. You will need inhaled bronchodilators (formoterol or albuterol) and inhaled corticosteroid (ICS) (budesonide or fluticasone).Don't worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
