My mom had a vein closure procedure done a while back but now at night she complains that her legs hurt her a lot any ideas or advice that i can help her with? it always starts hurting at night really bad and mild during the day.

Yes: Would encourage her to speak with the surgeon who performed this procedure. She should advise him/ her about her current symptoms.

Vein closure.: If new symptoms have developed a re evaluation would be indicated. I would start with a physical exam and a venous ultrasound to confirm that the treated veins are closed or if there is another reasons to explain her symptoms. See a vein specialist.
