The exact cause of lipodermatosclerosis is unknown. [3] [6] Venous disease, such as venous incompetence, venous hypertension, and body mass may be relevant to the underlying pathogenesis.

Between 40 and 80 percent of patients with cancer pain experience neuropathic pain. [1]Brain.

It causes swelling and pain in the legs, especially the calf, and (rarely) in the arms. [19] The superior vena cava (a large vein carrying circulating, de-oxygenated blood into the heart) may be compressed by a tumor, causing superior vena cava syndrome, which can cause chest wall pain among other symptoms.
