It seems like a superficial cut injury
in the leg. If the doctor, who stitched the wound up in his room, has examined it thoroughly and has found no injury to neurovascular bundle, then you are safe.
Please give adequate rest and time for the wound to heal. Do not start doing strenuous physical activity soon.
You can get an x-ray of the affected lower leg done to confirm that things are fine.
Wish you quick recovery.
