Is a Hot or a Cold Compress Best for Knee Pain?
Knee pain is one of the most common complaints that lead people to the doctor, but there are often things that can be done to relieve pain at home. Whether it is best to use hot or cold compresses for pain depends on the cause.
-
When to Use Cold
-
Ice is the treatment of choice for almost all knee pain, especially when associated with injuries, such as sprains and mild ligament tears. Use cold compresses for the first 24 to 48 hours to reduce swelling and inflammation.
How to Use Cold
-
Use a cold compress two to three times a day, for 20 to 30 minutes at a time. Use an ice bag or a bag of frozen vegetables wrapped in a dishtowel to protect the skin from direct contact.
-
When to Use Heat
-
Patients with conditions such as arthritis, may find relief from warm, moist compresses. Warm compresses help relieve stiffness and the associated pain. Warm compresses can also be used on injuries after 24 to 48 hours, alternating heat with cold.
How to Use Heat
-
Use an electric heating pad on a low to medium setting for 10 to 15 minutes at a time, several times a day. You may also use a microwavable bag, or make a hot compress with a towel soaked in hot water and wrung out until just damp. Apply to your knee until it begins to cool.
When to See the Doctor
-
There are some symptoms that should not be ignored. See a doctor if you cannot put weight on your knee or if the pain is unbearable. Seek medical treatment for large wounds, puncture wounds, and fever or drainage. Patients on blood thinners or who suffer from bleeding disorders should see a doctor if they experience swelling.
