I have urge to yawn whole day and when yawning stops or incomplete yawning it feels suffocative, and tighness in breathing and heart beat increases but I am not feeling difficulty from chest. I have enlarged nasal turbinates and I am not able to take deep breaths comfortably from nose. I have to do abdonimal breathing. Chest X ray is normal, Ecg normal, Cbc,
lft ,
crp normal. I have some issue of gastric trouble also. What is the cause of my excessive yawning?
