Generally speaking, Irritable Bowel Syndrome (IBS) itself does not cause back pain. However, patients with IBS often experience psychological stress, emotional anxiety, and insomnia, among other issues. Therefore, it is highly likely that back pain in these patients may be due to anxiety and insomnia, as a lack of restful sleep can lead to back pain. If a patient experiences back pain, it is advised to visit a hospital as soon as possible for comprehensive examinations to rule out the possibility of any organic diseases. Consideration of traditional Chinese medicine and herbal treatments can also be taken into account.
