16. Pains

Depression can cause a variety of mysterious pains. This can include headaches, aches in different parts of the body and even chest pains. Because these symptoms can be caused by serious physical ailments, they should never be taken lightly. Chest pain, in particular, should always be checked out by a doctor. Depression-linked pains can cut both ways: sometimes the pains are a symptom of depression, and sometimes people who suffer from pain-inducing physical ailments become depressed as a result. In any case, it pays to be cautious and investigate the source of the pain.
