question: My name is Ken Shea and I am 69 yrs old. 5 days ago I had a painful experience which lasted about 5 hours . The pain was in my upper abdomen in the center, about every 5 to 10 minutes , a sharp pain would begin and last for about a minute or so and then return . Bowel movement was very strange , but no blood in stool or the next day after short vomiting episode
