When the cause of Abdominal Pain is found to be non-pathological, an example being Irritable Bowel Syndrome. Or where the cause is just can't be found, the back & abdominal muscles may be the source.
Some people may have injured their abdominal muscles with excessive gym work.
It can be worrying when pain is felt at the back and also the front of the body, but this is often due to referred pain.
Pain arising from the abdominal muscles is frequently overlooked as a prime cause for abdominal pain.
There is an interesting link between IBS and Trigger Points in the Abdominal Muscles. The same nerves that supply the small and large intestines also supply the abdominal muscles.
When these trigger points are treated, the IBS will often settle down, it may even clear up completely.
When chronic pain effects the abdomen, it's well worth examining your diet.
Many people find it difficult to digest certain foods. Gluten, that is found in wheat and rye is a common culprit.
