[|Human|] i was hit in the forehead along my hairline on Monday ( i was playing in the pool with my son who is 2 and he threw a heavy plastic penquin water toy and hit me by accident)it did bleed some and a knot immediately came up.  today is Friday and the knot is still there and it seems to be a little more sore than it was in the beginning.  If it were a severe injury, would symptoms have shown up by now?
[|AI|]  Hello and welcome to Chat Doctor, Trauma is the cause of the injury. The knot caused by the trauma could is probably due to hematoma formation. Hematoma is caused by collection of blood at the site of injury. Hot compresses will help to resolve the hematoma. You can wait for a couple of days and take hot compresses and painkillers if required. The hematoma will resolve within few days. If it does not, you can consult your primary health care provider. Thanks and take care Chat Doctor.
