Help with Rectus Femoris Quadriceps Muscle Pain

Sombra Warm Therapy Gel provides pain relief. Warm Therapy Gel for Rectus Femoris Muscle Pain

Sombra Warm Therapy Pain Relieving Gel is a pain relieving gel that I use both personally and in my massage therapy practice. It provides warmth without burning heat and is great for relieving pain.  Applying Sombra to the muscles on the front of the thigh, down into the knee can help reduce pain and tightness caused by the rectus femoris muscle. I recommend Sombra for chronic pain and chronically sore tight quadriceps muscles.

Cold Therapy Gel For Rectus Femoris Injury and Pain

Biofreeze is recommended for recent muscle injury

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. If  your pain is from a recently pulled quadriceps muscle I would recommend Biofreeze.

cold-packThe Pro Ice Quad Multipurpose Cold Therapy Wrap is a good choice to provide cold therapy to both quadriceps and hamstring injuries. The wrap not only provides a consistent temperature but also provides compression which is important for reducing swelling and aiding in faster recovery.

The rectus femoris muscle can contribute to painful, stiff  buckling knees. The Professional Choice Knee Support is one of the best knee braces I have used. It provides support to weak buckling and painful knees while providing heat to help keep the muscle, ligaments, tendons and joint mobile. The two Velcro bands are adjustable and allow you to adjust the compression.  Although it looks bulky, it is comfortable and was made for people who ride horses who bend and straighten their knees for extended periods of time. It does not bind or pinch. If you are prone to knee injury and buckling knees I highly recommend this brace.




Sub Sports RX Graduated Compression Leggings – Men

Compression Leggings for Quadriceps and Upper Leg Muscle Support


Sub Sports RX Graduated Compression Leggings -Women

Compression wear is not just preventative wear for exercise. Compression wear can also aid in muscle injury support and reduce swelling during recovery time. If you are considering compression wear look for graduated compression. Graduated compression provides tight compression at the lower end of your limb and gradually decreases compressive force toward the top of the limb. This is important for circulation and inflammation reduction. The Sub Sports RX Graduated Compression Baselayer Leggings / Tights provide great comfortable compression at a reasonable price. The long leggings for men and long leggings or 3/4 leggings for women are a good choice for quad support during exercise or injury recovery. To properly support the quadricep muscles the leggings need to not only cover the thigh but must also go down past the knee as the quadricep muscles connect the hip to the knee. The Sub Sports RX Graduated Compression Leggings come in all sizes and have a choice of colors. Can be worn alone or under pants.

Massage Tools for Self Treatment of the Quadriceps Muscles


I recommend the  Tiger Tail 18″ Roller to use on both upper and lower leg muscles to help relieve tension and pain. I like the Tiger Tail for its ease of use and because it does not strain the wrists and hands. You do not have to contort into different positions or get on the floor or up against the wall to use this foam roller, simply roll it up or down the muscle. The 18″ is a good size to use on leg muscles as well as other muscles. The roller is also recommended by physical therapists, athletic trainers and doctors for self-treatment of muscles in between appointments. To use the Tiger Tail on the rectus femoris muscles start just above the knee and roll up covering the front of the thigh. Cover the entire front  including just to the inside and outside of the front thigh. Start with light strokes for a minute or two and build into more pressure and more time. Do not overdo as you can irritate the muscles!

Do you know that small knots in the rectus femoris muscle can contribute to the inability to straighten the knee, pain walking down stairs and restless leg syndrome?

If this pain pattern sounds familiar  I  recommend that you purchase Claire Davies  The Trigger Point Therapy Workbook: Your Self-Treatment Guide for Pain Relief.

It takes time and practice to master finding trigger points, but once you learn you have a tool and method to help relieve muscle pain throughout the body.  If you have unresolved knee pain, are unable to straighten your knee, or suffer from restless legs, it maybe trigger points in the rectus femoris muscle. Deactivating trigger points can reduce or eliminate this pain. This book is a must-have for anyone interested in finding the cause and treating muscle pain.
