Many people do not even report to their doctors that they feel depressed or that they have been experiencing other problems related to their despondent mood. The physical symptoms people feel are real, but they are caused by the illness of clinical depression rather than by another physical illness. Frequently, those who are depressed have chronic aches and pains. Headaches, stomachaches, and back and joint pain are common physical complaints. Others may have gastrointestinal problems such as indigestion, constipation and irritable bowel syndrome.
Some women contend with painful or irregular menstrual periods.
