HYPOCHONDRIA

"Hypochondria (illness anxiety disorder), sometimes called hypochondriasis or health anxiety, is worrying excessively that you are or may become seriously ill. You may have no physical symptoms. Or you may believe that normal body sensations or minor symptoms are signs of severe illness, even though a thorough medical exam doesn't reveal a serious medical condition. You may experience extreme anxiety that body sensations, such as muscle twitching or fatigue, are associated with a specific, serious illness. This excessive anxiety — rather than the physical symptom itself — results in severe distress that can disrupt your life."
