This is caused by postoperative incision edema. Try to control the number of erections and abstain from spicy food.

You can apply hot towel twice a day for 30 minutes each time to promote local blood circulation and accelerate edema regression, or wet compress with magnesium sulfate. The above is the suggestion of foreskin surgery and plastic surgery with braces, which has been done for 7 days. I hope it helps you, and I wish you health!
