Hi, My 5 year old son, got a kick to his penis by his older brother.  He immediately started to cry and then went to go to the toilet.  However, the tip of his penis seemed to be bleeding - Im not too sure if the blood was in the urine or on the tip of his penis.  This happened approx. 2 hours ago - he has not gone to the toilet since this happened.  Should I bring him to the doctor immediately - I was going to wait until he requires to go to the toilet and check to see if there is any blood. I am also concerned of any long term effects this may have on him.  I am extremely worried.
I understand your concern. As you say the bleeding started soon after the kick, and it is likely to be a traumatic bleeding from his prepuce (foreskin) It is unlikely to be from any internal bleeding as I have seen Hun Chat Doctor. You can slowly examine the tip of his penis and retract the skin to see if there is any injury and if there is you can apply an antibiotic cream If the crying stopped and the child plays normally you have to just watch him if the bleeding returns, in which case you can show him to your doctor. Long term effects are unlikely and not seen usually
