I m 38 years old and since the beginning of last year I ve had episodes of dry heaves. It s not associated with nausea but it seems to start in my nasal passages and throat. Everything seems stopped up and if I swallow my saliva feels thick and difficult to get down my throat so I start gagging and try to swallow and it feels tight so I continue to gag until I can manage to calm down. It frightens me because it seems like it s difficult to breathe. I ve had an endoscopy last year for stomach pain, an MRI/MRA this year for headaches and dizziness have minimal allergies although I take Benadryl to help me sleep and I have a history of TMJ/Myofascial Pain Disorder and anxiety. Can you tell me what it could be? Oh, the endoscopy was normal and the MRI/MRA didn t show anything like tumors and aneurysms.
