 | | Secondary erythromelalgia may occur in patients who have myeloproliferative disorders, hypertension, venous insufficiency, diabetes mellitus, SLE, RA, lichen sclerosus et atrophicus, gout, spinal cord disease, or multiple sclerosis. |
 | | Diagnosis of erythromelalgia is based on the relationship of complaints to increased skin temperature. |
 | | Because erythromelalgia may precede a myeloproliferative disorder (even by several years), frequent blood counts may be indicated to allow early diagnosis and treatment of the latter. |
