Hernia surgery requires no strenuous activity for 3 months, and if you want to run, you usually have to wait until after 3 months. Nowadays, hernia surgery is mostly done by tension-free hernia repair, which is like putting a patch on the surface of a torn shirt. Hernia is caused by a defect in the muscle of the abdominal wall, through which the contents of the abdominal cavity enter into the subcutaneous, or even into the scrotum, and a mass can be seen on the surface. The purpose of the surgery is to repair the defect in the abdominal wall, and nowadays, synthetic mesh is mostly used to repair the defect in the abdominal wall. Theoretically, after a week of hernia repair, the patch can heal with normal tissue, but to heal completely and firmly, it usually takes at least 3 months. 3 months later, the body will be completely back to normal, and the body is as strong as it was before the surgery, and you can run at this time.
