Circumcision swelling

Sarah

Hi all - I am a FTM and had our little boy circumcised after he was born just over three weeks ago. It has been healing so well but noticed that just under the head was swollen last night. I am concerned because it's been about three weeks and now suddenly it's swollen. Swelling has not increased since I noticed it but not sure if I should be concerned or if this is part of the healing process. I have a doctors appointment Monday, but big sure if I should wait till then to have it looked at if swelling does not increase. Any ideas?
