Infected knee?

My 10-year-old son had a bad cut on his knee. After going to the local doctor he applied paper stitches and gave a tetanus injection. My sonís knee has now become very swollen and looks like it has fluid in the knee. Can you advise?

You should bring your son back to your GP. The swelling of the knee raises the possibility of infection and your son may need antibiotics. It is possible that the infection has spread into the joint so this matter needs to be attended to quickly.
