Thank you for your question.
I am not a medical professional and would not be able to give you medical advice.
It is good that you contacted your doctor and I am glad there is nothing physical causing this. Sometimes people with anxiety do feel as if they have a lump in their throat and that can make them feel like they are gagging. But from what you have said, this doesn't sound the same.
I would not know what this is. You might try speaking with an Ear Nose and Throat specialist to see if they have any answers.
I am sorry I did not respond to your letter until now. I am glad you have posted this publicly so that you can get more responses.
Have you read my article about gagging? I am not a doctor but when you talk about your symptoms I am wondering if this has to do with your breathing or when you say you exert yourself. I would suggest that you create a log of when this happens and under which conditions...does it happen when you exert yourself in other ways such as running or other types of exercise? Take this log with you to an ear, nose, and throat specialist to rule out any medical problems there. Anxiety can cause this reaction but it seems that you are not feeling anxious when this happens.
I wish you the best of luck and hope you discover the cause. Let us know what happens.
