How It Feels
You may notice a brief, sharp pain when the intravenous (IV) needle
is placed in a vein in your arm. The
local anesthetic sprayed into your throat usually
tastes slightly bitter and will make your tongue and throat feel numb and
swollen. Some people report that they feel as if they cannot breathe at times
because of the tube in their throat, but this is a false sensation caused by
the anesthetic. There is always plenty of breathing space around the tube in
your mouth and throat. Remember to relax and take slow, deep breaths.
During the test, you may feel very drowsy and relaxed
from the sedative and pain medicines. You may have some gagging, nausea,
bloating, or mild abdominal cramping as the tube is moved. If you are having
pain, alert your doctor with an agreed-upon signal or a tap on the arm. Even
though you won't be able to talk during the procedure, you can still
communicate.
The suction machine used to remove secretions may be
noisy but does not cause pain. The removal of biopsy samples is also
painless.
You will feel groggy after the test until the medicine
wears off, usually in a few hours. Many people report that they remember very
little of the test because of the sedative given before and during the
test.
After the test, you may belch and feel bloated for a while. You may
also have a tickling, dry throat; slight hoarseness; or a mild sore throat.
These symptoms may last several days. Throat lozenges and warm saltwater
gargles can help relieve the throat symptoms. Do not drink alcohol after the
test.
