I'm a medico. My mother noticed as having varicose veins 5 months back. Swellings on posterior aspect of knee and surrounding areas. Veins can be traced as greenish colur. No pedal oedema / lipodermatosclerosis/ venous ulcer. Severe pains if standing >30 min. Pain relieves on rest. Plz suggest apt treatment for this stage of varicose veins and treatment costs associated.
