Can somatization disorder cause leg swelling?
Generally, somatization disorder may indirectly cause a sensation of leg swelling, but it does not typically lead directly to organic edema. If obvious swelling occurs, other underlying causes should be ruled out. Seek medical advice promptly if abnormalities are present. Detailed analysis is as follows:

Some patients with somatization disorder may experience abnormal bodily sensations, interpreting feelings of leg soreness or heaviness as a "swelling" sensation. However, physical examinations reveal no significant fluid retention. This condition is often related to perceptual distortions caused by psychological factors, and the sensation of "edema" may worsen or subside with emotional fluctuations.
However, if measurable swelling (such as pitting upon pressure), changes in skin temperature, or pain are present in the legs, these are more likely due to organic conditions—such as venous return disorders, kidney disease, or endocrine abnormalities. Such types of edema are not directly associated with somatization disorder and require medical evaluation to determine the exact cause.
If leg swelling occurs, it is recommended to first visit a hospital for a physical examination to rule out organic diseases. If no abnormalities are found and other somatic symptoms are present, further consultation with a psychiatrist or psychologist is advised to assess potential links to somatization disorder.
