Flexor Digitorum Superficialis Muscle: Palm and Finger Pain

(Last Updated On: August 10, 2018)

Sharp stabbing pain is felt in one or any combination of the four fingers. This pain will sometimes radiate up into the palm and wrist. The flexor digitorum superficialis is also known to cause “trigger finger” where the finger locks in a bent position.

What are the pain and symptoms associated with the Flexor Digitorum Superficialis Muscle?

  • Sharp pain is felt on the inside (palm side) of one or all four fingers
  • Pain will sometimes extend up into the heel of the hand and wrist
  • Is a major contributor to “trigger finger”: finger locks in bent position
  • Uncontrollable twitching in the fingers

Where is the Flexor Digitorum Superficialis Muscle muscle located?

The flexor digitorum superficialis attaches the bone of the upper arm (humerus) runs down the inside of the forearm  and connects via four tendons to the four fingers (phalanges).

What movements do the Flexor Digitorum Superficialis control?

  • Bends the fingers down toward the palm
  • Helps bend the wrist down

Help with Flexor Digitorum Superficialis Muscle Finger Pain

Cold Therapy Gel For Flexor Digitorum Superficialis Hand and Finger Injury Pain

Biofreeze Pain Relieving Gel is a cold therapy gel that provides pain relieve for new injuries and is great as a maintenance treatment for overuse and repetitive use injuries such as tennis elbow. Cold therapy should be used on new and recent injuries instead of heat as it cools the area much like ice and does not promote swelling. A recent study showed that Biofreeze decreased pain 2 times more than ice and the pain relief lasts 9 – 10 longer. Many who suffer from arthritis pain like to use Biofreeze on swollen painful joints. If you have recently injured the flexor digitorum superficialis muscle or have unexplained pain that has started in the fingers, use Biofreeze. Rub the gel around the elbow, down the pinky side of the forearm and into the wrist and hand.

Cold Compression Sleeve For Forearm Pain

Freeze Sleeve Cold Therapy Compression Sleeve is recommended by medical professionals for treatment of injury, recovery, and over-use soreness. The sleeve provides total circumference cold therapy and compression that other cold treatments do not provide. The sleeve slides on and features material that can be worn on bare skin, allowing you to be mobile during treatment. It can be used for most areas of the arms and legs.

Warm Therapy Gel For Flexor Muscle, Arm, Elbow and Hand Injury and Arthritis Pain

For arthritic or chronic shoulder, arm, elbow and hand pain relief I recommend Sombra Warm Therapy Pain Relieving Gel. Sombra provides warmth without burning and is better at relieving pain than other over the counter pain creams. Apply Sombra to the inside of the elbow, down the inside of the forearm, wrist, palm and fingers to treat flexor digitorum superficialis pain.

Full Arm Compression Sleeve for Elbow, Forearm and Wrist Pain

The CompressionZ Compression Arm Sleeves are for those who want or need more support for muscle injury, muscle recovery or lymphedema. The sleeves work well for those who have chronic elbow, forearm and wrist pain due to repetitive motions that can irritate the extensor muscles in the arm. The sleeves work well for athletes as well as people whose jobs require repetitive twisting motions of the wrist. The sleeves are available in 3 sizes and a variety of colors. Be sure to read the size chart and follow the instructions to ensure proper fit. Two sleeves per package

Compression Band for Tennis Elbow, Golf Elbow, Carpal Tunnel Syndrome, Repetitive Stress Injuries

The BandIT Forearm Band is worn by many professional athletes to prevent and relieve muscle pain caused by repetitive motions of the elbow and wrist. The BandIT uses selective pressure on the forearm muscles without cutting off circulation, limiting range of motion or causing swelling around the band. Though I do not recommend this as a long-term treatment or for long-term wear, the BandIT can help relieve pain for athletes to help get through a game or for those who suffer from carpal tunnel syndrome that want pain relief while typing to make a deadline. Read and follow the enclosed instructions for temporary relief from forearm, wrist, hand, and finger pain.

Compression Gloves For Support, Warmth and Pain Relief

Whether the pain in your hands is caused by a muscle injury or arthritis, compression has been shown to help with pain relief. The Imak Compression Arthritis Gloves are some of the best on the market.

The gloves provide gentle compression which helps decrease both pain relief and inflammation. The seams of the gloves are sewn to the outside so you will not have irritation or discomfort. The fingers opening are reinforced so that they will not fray with wear or during washing. I like this particular brand because the gloves are easier to get on and off than most other compression gloves. Reasonably priced too!
