<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have some drainage but my main issues are the feeling of a lump at the base of my throat no trouble swallowing and a tightness in my chest when I try to take a deep breath. I am not short of breath just feel like I can t expand my lungs enough to get a deep breath  <response>: Thanks for asking your question first thing that need to be done is quit smoking if you smoke it seems like you have bronchial asthma allergic rhinitisallergyupper lower resp tract infection these are the possibilities but to confirm you have to consult a Pulmonologist who can request for a chest X-ray, sputum culture and if needed a spirometry which can lead to a diagnosis in my patients I apply the same protocol and start them on empirical antibiotics and a proton pump inhibitor and some bronchodilators like aerosol which relieves the symptoms no need to panic thanks feel free to ask more questions
