Hi.
Thanks for your query.
Read the history and understood the problem.
I am sorry to know that you are suffering from such a severe stabbing pain with
vomiting for the last 4 years. It is difficult to understand why have you not investigated or consulted a Gastroenterologist.
This is occurring only during night time and makes you curl on, meaning it is so severe.
The most probable causes are:
Vascular insufficiency to the intestines after the dinner- the requirement of blood supply increases many folds .
Internal hernia, again very difficult to diagnose.
Volvulus of some part of the intestinal tract.
To get a proper diagnosis you should be seen by a Doctor / Gastroenterologist- preferably - during the attack. The investigations done when not in attack may turn out to be normal.
I would advise the following investigations strictly to be done during the attack of pain.
-X-ray of the whole abdomen in standing position, this helps to have a suspicion about the
intestinal obstruction and the cause of it.
This is followed by
CT scan next time to confirm the diagnosis.
Exploratory Laparascopy or
Laparotomy. This helps tremendously for the diagnosis and treatment too.
