[|Human|] I m a former smoker( I quit March 2013) who is now experiencing breathing problems. I have a nebulizer that I use, it has not helped. My (R) lymphnode in my neck keeps swelling and my heart keeps beating fast and slow without doing any activity, and I ve been having these symptoms for about a month. What do you think?
[|AI|]  Thanks for your question on Chat Doctor. In my opinion you should get done chest x-ray immediately.  Since you are smoker and worsening of breathing even after nebulization suggest1. Infection2. Malignancy causing collapse of lung. Chances of malignant lesion are high as you are also having enlarging cervical lymph node on right side. This can be a malignant lymph node due to spread from lung primary. So Fine Needed Aspiration Cytology (FNAC) is needed from lymph node. So get done chest x-ray and FNAC.
