I would suggest you to take following measures:

Do exercise regularly as it improves the circulation of blood.

Use support stockings as it promote blood circulation and limit the movement of fluid. Almost each drug store or medical shops carry these stockings.

Avoid standing and walking for long period of time.

Review your medication with your doctors.
