Your information suggests that the problems you have had since the surgery were probably caused by the surgery. Some of your symptoms may be caused by the location of the 2 benign tumors. They may be close enough to the vagus nerve to be irritating to it and other nearby nerves.
I suggest that you consult with a head and neck surgeon with great experience. You can find one at the Memorial Sloane Kettering Hospital in New York City or the MD Anderson Hospital in Houston, Texas
The vagus nerve may have been damaged, during the surgical removal of the tumors. The vagus nerve and its branches control many, many, body parts, including small intestine, stomach, esophagus, vocal cords, etc.
If I were you, I would ask your surgeon about whether the vagus nerve (or branches of the vagus) was possibly damaged during the surgery, possibly contributing to your coughing & choking episodes.
Also, ask the surgeon if the tumors might possibly be returning, pressing on your vagus nerve, etc.
You can also speak with a LUNG LINE nurse, by calling the LUNG LINE, at 1-800-222-LUNG(5864), between 8am & 4:30pm, Mountain daylight savings time.
Good luck to you!
Sincerely,
Concerned lady
