Vitamin B have analgesic role in some neuropathic pain conditions.This study aimedto evaluate the relationship between vitamin D and vitamin B12 levels and neuropathic pain in lipedema.
In this cross sectional study 200 lipedema patients will beincluded. According to painDETECT questionnaire scores of cases with lipedema patients will be divided into two groups;An overall score of > 13 likely or possible neuropathic pain (group 1) and <13 unlikely NP (group 2). Patients' age, gender, comorbid diseases and laboratory values (25 OH vitamin D and vitamin B12 levels) will be recorded.
