Because the operation is circumcision, there must be blood vessels to be broken and lymphatic tissue to be broken. So it is normal to have interstitial fluid (edema). I don't know about your postoperative wound care, such as avoiding stimulating erection, using antibiotics to diminish inflammation after operation, and taking antibiotics orally. If used improperly, the drug effect will not reach the anti-inflammatory effect, and it will also indirectly cause edema.
Also, you should distinguish between edema and postoperative scar. It is best to go to a surgical hospital for treatment. Edema will subside sooner or later, and there is no such thing as edema will never disappear.
