I Have A Lump Above My Hyoid Bone . In
Zenker diverticulum
Detailed Answer:
Hello and thank you for using “Ask a doctor service” for your health related questions.
I understand your concern. The symptoms you describe might be due to a condition called Zenker diverticulum or pharyngoesophageal diverticulum. This is pouch inside the throat, in the junction between the larynx and he esophagus, cause by relaxation and weakening of the throat wall. It may cause difficulty swallowing, a sensation of a lump in the neck, food getting stuck, smelly breath, coughing especially during the night, a voice change.
It is diagnosed by a barium swallow, so it is good that you are already scheduled for one.
I hope this answers your question. Let me know if I can assist you further.
Take care
