 [ Symptoms ] if my headache has lasted for 5 days and nothing is helping should i go to a doctor  i have had a headache for a little over five days i was also diagnosed with a pitituary cysit a few years ago no otcs are helping nor are my perscriptions it keeps getting worse my joints hurt and i keep getting muscle cramps [ Disease ] i am not sure what you mean by this exactly every person has a large intestine and a small intestine these are sometimes called the large bowel and small bowel  they small bowel is literally smaller in diameter than the large bowel this is normal the small intestine is where most of the nutrients from food are absorbed the large intestine serves mainly to extract water and consolidate fibrous waste products left over after food passes through the small intestine these waste products then are passed out of the body as stool so it is perfectly normal to have one bowel bigger than the other it should not cause you any problems wishing you well
