Dr Sebastian didn't listen or discuss anything. When I expressed concern for pain he said I have to go farther take a deep breath. From others I've spoken to this procedure usually isn't that painful. In theory the Ativan and Lidocaine should have helped but it seemed as if no medication had been administered. This was worse than other biopsies, colonoscopies or any other procedure I've had. |
