Thirty-four days after circumcision, a hard circle in the incision may be the result of postoperative scar formation or the presence of infection at the wound site. The scar will form and become more obvious within 1~2 months after circumcision, but as the wound heals, the scar will soften and disappear on its own in about six months; after surgery, you should pay attention to personal hygiene and care, pay attention to rest, and don’t get involved in too strenuous activities. If the wound is hard after the operation, it may also be due to problems such as inflammation, poor wound healing, accumulation of blood and fluid, etc., then it needs to be sterilized, anti-infection and further treatment. If scarring occurs do not be overly nervous, because the skin as well as the soft tissues will repair themselves; eat a diet rich in nutritious foods high in vitamins and avoid spicy and stimulating foods. If you feel unwell, you should go to the hospital in time and consult your physician for guidance.
