Help For Popliteus Muscle Knee Pain

When dealing with knee pain one of the first treatments many consider is a knee brace. While a brace may help with other types of knee injury and chronic pain, a brace or wrapping is usually NOT recommended for the popliteus muscle or other pain behind the knee. Do not wrap or use a brace unless it is recommended by a medical professional. 

Cold Therapy Gel for Popliteus Muscle Pain

Biofreeze Pain Relieving Gel is an excellent pain relieving gel and I recommend it for those who have sudden onset muscle pain or recent injuries. It is better to use than warm therapy gels and creams for muscle pain caused by inflammation as it cools the area much like ice. A recent study showed that Biofreeze decreased pain 2 times more than ice and the pain relief lasts 9 – 10 longer. To treat popliteus pain, rub Biofreeze around the knee, making sure to cover the area behind the knee.

Cold and Warm Therapy Wrap for Popliteus Muscle Injury and Sudden Onset Pain

If you suspect you have injured the popliteus muscle or have sudden onset pain behind the knee, cold therapy should be your first course of treatment. I recommend the The Simple Spectra Clay Hot/Cold Wrap for use with behind the knee pain. Using a pillow to prop up your leg, place the cold pack between the pillow and the back of your knee. The pillow provides support for the knee and will help keep the knee slightly bent to provide better treatment and relieve muscle stress. You can use cold therapy for 20 minutes per hour for the first 48 hours. Do not use cold therapy for more than 20 minutes at a time as longer use of ice or cold packs can cause tissue damage. The packs can also be used for heat treatment. It is a multi-use pack and can be used for most areas of the body.

Warm Therapy Gel For Popliteus Muscle Pain

Sombra Warm Therapy Pain Relieving Gel is a favorite of my clients for warm therapy and pain relief for muscle pain. Sombra heats comfortably without burning and begins providing pain relieve within minutes. It can be applied several times a day if needed and is excellent for arthritic knees. Do not apply Sombra before using a heating or cold pack as it can cause blistering to the skin.

Self Treatment for Popliteus Muscle Knee Pain

Do you know that small knots, taunt bands and other dysfunction in the popliteus muscle can cause pain behind the knee and make it difficult to fully straighten or lock the knee?

These knots or tight bands are called trigger points and if left untreated can cause deep aching in the back of the knee. A trigger point in the popliteus muscle is often the cause of pain behind the knee after ligament and tendon surgery. If you have unresolved pain behind the knee I recommend Claire Davies book The Trigger Point Therapy Workbook: Your Self-Treatment Guide for Pain Relief. Mr. Davies explains trigger points and muscle pain in plain everyday language that is easy to understand. His diagrams and instructions help you find and treat trigger points throughout the body. If you are dealing with pain behind the knee and have not been able to find an effective treatment, I highly recommend this book. It takes time and practice to master finding trigger points, but once you do, you will have an effective self-treatment for not only knee pain but for muscle pain throughout the body.
