The foreskin operation is a very small operation. Generally, within 7 days after operation, the edema is serious, and there will be symptoms such as swelling, pain, edema and exudation. After 7 days, the edema gradually subsided, and the wound healed and scabbed off within 2 weeks. However, the wound edema still exists, and it takes 2-3 months to completely subside. This period of time will not affect normal life, and it will recover in a month. Without treatment, it can subside by itself, and the most important thing after operation is nursing, disinfection every day to prevent infection, to prevent the erection from tearing the wound, and it will hurt after erection, and it will not hurt after 7 days. It is not recommended to use drugs to prevent erection during this period, which can be tolerated. Medication is not good for your health, and you will soon get better.
