Why is my son suffering from severe pain after chemo? My son had his first chemo today. R-CHOP. He is suffering from severe abdominal pain. and a bit of fever. Is this normal. Any answer please.

Please seek medical attention. You shouldn't be having abdominal pain.

this is a fix it online request forum ---have your son notify a doctor

strange that the oncologist could not answer this question

Abdominal pain is caused by inflammation (for example, appendicitis, diverticulitis, colitis), by stretching or distention of an organ (for example, obstruction of the intestine, blockage of a bile duct by gallstones, swelling of the liver with hepatitis), or by loss of the supply of blood to an organ (for example, ischemic colitis). To complicate matters, however, abdominal pain also can occur for unclear reasons without inflammation, distention, or loss of blood supply. An important example of this latter type of pain is the irritable bowel syndrome (IBS). These latter types of pain are often referred to as functional pain because no recognizable (visible) causes for the pain have been found.

There are several causes possible, some of them more serious. The only thing to do here is to go see a doctor, and tell all. The doctor may feel your tummy, and possibly order tests.

Make sure to say whatever you have eaten, and any activities like strenuous exercise, at the time the pains began.

metamusil

This is an extremely common side effect of pregnancy. During pregnancy you have a few reasons for this:
1) Increase in progesterone, decreases the contractility of smooth muscle. Smooth muscle is what makes up the bulk of your Gastrointestinal Tract. This decreased contractility will lead to nausea, constipation and sometimes cramping.
2) Increase in abdominal size will lead to pressure on the GI tract especially the stomache causing heart burn and slowed emptying of the stomache.

Good Luck! I hope this helped!
