Is it normal to have to cough when you bend your neck, such as looking down at the floor? I am 52, female, 5'2", 123#. I also get phlegm in my throat, especially after eating or talking a lot. I recently had a biopsy of a lump in my neck (just left of trachea) that they said could have been branchial cleft cyst or Warthin's tumor. Thank you.
