How do you stop inflammation from the knee?

Ice is always what doctors recommend. Alternating between ice and heat every 20 minutes or so also helps with aches. Depending on how intense the pain is, taking something like Aleve (Naproxen) is also very helpful for minor pain and discomfort. If pain is more chronic, you may want to consider wearing a knee brace while you exercise or put any kind of pressure on it.
