How To Get Rid Of Knot Caused After Hitting Door?

Hello,

Last Sat my son ran into the door frame and it left a nasty knot, It is almost a week later and he still has the knot, it didn't break the skin but I can see that it looks as if blood is trapped inside. Should I take him to the Doc. or will this knot go away on it's home, could this end up being permanent?

Hello dear,

The knot formation after a trauma is due to accumulation of fluid & blood and it is called Hematoma.
The blood cells accumulated are eventually broken down and absorbed in the body.
But this is a slow process & takes times to disappear completely.
Till that time, symptomatic relief is obtained by taking analgesics, ice compression & adequate rest.
If it still persists or there are any other associated symptoms like vomiting, loss of consciousness, convulsions, etc...then it will be better to consult his Doctor.

Wishing your son a good health.
Take care.

Hello,
If the knot doesnt diappear in another few days, see a doctor. Use ice fomentation several times a day. If there is discolouration, then may take some times to go away. If there is blackish discolouration see a doctor.
