around the left side of my collarbone, there is a puffiness with some discomfort..it does bother me with some slight chest discomfort as well..My Doctor said it was the top of my lung being pushed up...due to constipation, bloat, etc...she did not listen to my lungs or heart, and the reasons for it to be pushed up did not apply...I get short of breath and lightheaded...Im confused
Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, possibility of lymph node enlargement and related swelling is more in your left collarbone. So get done ultrasound examination of neck to know confirm this. For shortness of breath and weakness, possibility of bronchitis is more. So 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 may need inhaled bronchodilator and inhaled corticosteroids (ICS). Don't worry, you will be alright, consult doctor and discuss all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
