When i sit with my feet down or stand my toes start turning red and they start to burn/throb until i sit with foot up then it goes away?

Dependancy: Rubor on dependency (red toes with feet down) with subsequent burning or pain is a sign of Peripheral Vascular disease. This may be a mild symptom or more serious. Smoking, anxiety and temperature changes also effect small vessel disease. If dependent swelling (edema) is also noted then support hose may be helpful. Avoid tobacco, temperature extremes and non-supportive shoe gear.
