No an endoscopy is not painful. Your doctor will have you asleep for the procedure. I recently had one myself and didn't feel a thing. When you wake up your throat might be a little sore but that passes quickly. It is a very quick procedure, no more than 15 to 20 minutes. Just make sure you have someone to take you home due to the anesthesia may make you off balance. The doctor will let you know right away if he found anything and give you any instructions on what to do. I hope this information helps.

Depending on what the doctor is looking for, it usually takes about 20 minutes. They have you lay on you back then on your left side. It's like getting an intense Ultrasound. It's not painful. If they find something they have you wait so the doctor can look at it right then if not you can leave. I hope this helps. You usually have an appointment with the heart doctor right after the procedure.
