Son"s swollen leg, should I worry??

[MissHooliesclassmonitor]

2 weeks ago my son tripped over and hit his upper shin/knee on some wood. It is still raised quite swollen and hot to the touch. I only realised this yesterday when I saw it. Years ago my brother was hospitalised with a inward bruise that didn't go (sorry can't think how else to explain it!!) and I am a bit worried about similar happening as the doc thought my brother may get a blood clot.
Any advice appreciated X

Sounds like it definitely needs looking at. Have you googled it?

Yes but can't find much information. Will contact docs tomorrow. Mainly the heat in the swelling that is worrying me, but he's not in pain. Thanks for your response ThatsWhatSheSaid X

Heat to me would suggest an infection, I would get it checked out tomorrow- do you have a walk-in clinic nearby?

Hi watermelon, not a walk in clinic but my doctors are good and will see kids really quickly X

Waterlemon not watermelon sorry
