How It Feels
You may feel a brief sting or pinch from the numbing medicine. Most
people do not have pain when the catheter is in the blood vessel.
You may feel pressure in the blood vessel as the catheter is moved.
Let your doctor know if you are having pain.
You will probably feel some warmth when the dye is put in. This
feeling lasts only a few seconds. For some people, the feeling of heat is
strong and for others it is very mild.
You may have a headache, flushing of the face, or a salty or
metallic taste in your mouth after the dye is used. These feelings do not last
long. Some people may feel sick to their stomach or may vomit, but this is
uncommon.
After the test, you may have some tenderness and bruising at the
site where the catheter was inserted.
You can drink extra fluids to pass the dye from your body unless
your doctor has told you not to.
