Dear Ms. Tisha
Thanks for writing to us.
my first thought is that you should see your doctor on priority. reasons are 1. listlessness 2. difficulty in breathing 3. pain in shoulder region on cough
or sneeze 4. Lymph
nodes in axilla/ neck 5. history of chronic smoking
all these needs to be evaluated and worked up. so please see your doctor urgently.
feel free to discuss further.
