The answer depends on how hard the individual was punched, the angle of the punch, and the location. Hits to the head or face do not always lead to bumps immediately. In fact, sometimes bumps do not form at all. It is possible, however, for bumps to form within seconds to minutes after impact.
I hope that answers your question. Please let me know if I can help with anything else.
It would be extremely difficult and almost impossible to determine the exact cause of the head trauma based upon bruising alone. Rarely patternes can be seen such as hand prints or knuckle prints. But this would have to be observed by a doctor or law enforcement agent to be certain. The bruise could result from any head trauma whether punched or if someone fell and hit their head or banged their head on a cabinet. Any of these could produce bruising.
The bruising along with history would be the best way to determine if the bruising was the result of a punch.
If you or someone you know was punched or assaulted, I suggest you contact your local police department to report this or go to a local clinic/hospital to have the injury investigated.
Thanks for clarifying.
It is unlikely that the black eye developed after an open handed slap. However, it is possible. If she was hit with enough force, the blood vessels could have broken and caused bruising. The vessels around the eye are fragile and black eyes can form from head injuries in general. Bruising could possibly be more noticeable 24-48 hours after the initial injury. That said, if the trauma was significant enough to cause a large bruise and swelling around the eye, this would most likely have been seen sooner.
I recommend you contact a local medical expert who may be able to see the pictures and do a little more physical exam to determine if the extent of the injuries were secondary to an open handed slap.
There would most likely be evidence of a punch 60 minutes after the incident if it were a hard punch.
If the slap was with little force and along the jaw line, a swollen bruised eye would be unlikely.
I still Iecommend you contact a local medical expert who may be able to see the pictures and do a little more physical exam to determine if the extent of the injuries were secondary to an open handed slap.
I hope that answers your question.
Hello again. Sorry, I was offline for a while.
Bruising may not be detected within 30-60 minutes after the slap, but there would most likely be swelling and redness. If the slap were hard enough, bruising would occur some time later.
