Have a Water Contrast Bath
This technique consists of an alternation between heat and cold, where the objective is to promote circulatory function and also helps the elimination of fluid from the affected body parts. [4] Blood vessels dilate when heat is applied, and narrow when cold is applied. This change in the caliber of blood vessels stimulates circulation.
Prepare two basins with water. One with hot water around 40 ° C to 45 ° C (try placing your elbow in the water, as you do to check a baby bath). Keep the hot water at the desired temperature, adding more hot water as needed.
The other basin should have water with some ice cubes at approximately 15 ° C (cold, but bearable).
Place the affected body part (your feet) completely in hot water for 3 minutes. After 3 minutes, switch to cold water for 30 to 60 seconds. Repeat 3 to 5 times, ending with the cold bath.
