You can't do strenuous exercise for at least half a year after varicose vein surgery. You can do light exercise after two months, but you'd better not run. You can walk. It is recommended to rest as much as possible after operation, and running is not recommended. Running is not easy to cause the recurrence of disease. Try not to stand for a long time at ordinary times, take more rest after operation, and go to the hospital for review regularly.
