Treatment of knee pain depends on the cause of the knee pain. If you have been working on your knees all day then potentially rest and anti-inflammatories such as ibuprofen can help. If the cause is trauma and there is possible joint damage then you should seek medical attention.
Stop, change, or take a break from any activity that may be causing your pain or soreness. When resting, place a small pillow under your knee. Ice will reduce pain and swelling. Apply ice or cold packs immediately to prevent or minimize swelling. Apply the ice or cold pack for 10 to 20 minutes, 3 or more times a day.
