The vastus intermedius muscle is a deep muscle that lies under the rectus femoris on the front of the thigh.

Trigger point pain tends to concentrate in the middle of the front of the thigh. The pain can radiate up into the fold of the thigh. It can also travel down the leg to the top of the knee.

Pain caused by a muscle strain can occur anywhere along the muscle that runs from just under the hip joint to the knee.

Though muscle strain and trigger point pain can be similar, treatment for each is different. It is important to determine if the muscle pain is a strain or trigger points, so the proper treatment is applied.

    Vastus Intermedius Trigger Points Symptoms:

    Vastus Intermedius Referred Pain Pattern

    Trigger points in the vastus intermedius affect the knee and can cause pain to radiate into the inside of the lower thigh.

    Other symptoms include:

    • Pain down the middle of the front of the thigh
    • Significant increase in pain when walking
    • Pain increases when climbing stairs or walking up an incline
    • Problems straightening the knee after sitting

    Biofreeze Professional Gel is recommended by medical professionals and trainers for the pain and symptoms of muscle strains. It provides excellent pain relief and may help reduce inflammation caused by a strain. 

    What Causes Trigger Points To Develop In The Vastus Intermedius?

    • Runners and joggers frequently develop TrPs in the muscle due to the repetitive movements
    • Squats and other exercises that require bending and straightening the knee repetitively
    • Sitting for long periods
    • The vastus intermedius will develop TrPs if there are trigger points in the rectus femoris, vastus medialis, and vastus lateralis.

    Trigger points also develop after an injury to the muscle or muscle imbalances in the hips and legs.

    How To Avoid Development of Trigger Points In The Vastus Intermedius

    • Warm-up before running, sports, and exercise
    • Stretch upper and lower leg muscles after running and exercise
    • Don’t try and go past your muscles limits when doing squats

    Vastus Intermedius Trigger Point Treatment

    Many massage therapists, physical therapists, chiropractors, and sports medicine doctors are trained in trigger point therapy. They can show you how to find and treat specific trigger points that may be troubling you.

    You can also learn trigger point therapy with the help of The Trigger Point Therapy Workbook.

    It is one of the best resources to learn how to find and treat your trigger points. It takes time, patience, and practice to learn how to find TrPs, but once you learn you can have the skill to self-treat a lot of muscle pain throughout the body. The key to successful trigger point treatment is consistency. Most trigger points respond best to several 1-2 minute treatments a day.

    The vastus intermedius muscle lies under the rectus femoris muscle, and if you have muscular legs may take a little more pressure from your hands to treat than other muscles. If you have problems with pain in your hands, you may want to purchase a Knobble or Thera Cane to use during treatment.
