Pain In The Middle Knuckle Of The Finger Symptoms

Pain in the middle knuckle of the finger, or any finger, is usually the result of swelling. Swelling is the result of fluid buildup that gets trapped in your body’s tissues. Most people first notice swelling because the affected body part may appear larger than normal.

Common characteristics of pain in the middle knuckle of the finger

Often a painful or swollen middle finger can be easily identified by comparing its size to the size of your other fingers; however, sometimes the swelling may not be visibly obvious and difficult to discern.

Common accompanying symptoms

If your pain is not accompanied by obvious swelling, you may experience other symptoms that may include:

  • Stiffness
  • Limited range of motion
  • Stretched or shiny skin
  • Skin pitting: Skin that dimples or pits after pressing on the affected area for a few seconds
  • Warmth or redness of the affected area
  • Visible deformity

If you notice any of these symptoms, make an appointment with your doctor promptly in order to follow up on your symptoms, get a diagnosis and receive appropriate care.

Pain In The Middle Knuckle Of The Finger Causes

Any condition that causes accumulation of fluid in the tissues of your finger will cause swelling and accompanying pain. Swelling can occur throughout the body due to a variety of causes, but swelling in just one part of the finger has limited triggers. A swollen finger or painful middle knuckle may not seem serious initially, but without prompt medical follow-up and care, your symptoms could worsen.

Inflammatory

Pain in the middle knuckle of the finger is often the result of injury and the resulting inflammatory response.

  • Rheumatologic: This category includes inflammatory conditions involving the body’s tissues and joints. Conditions such as arthritis and gout cause inflammation that easily brings fluid into the tissues leading to swelling, redness, and tenderness of single fingers and often the big toe [1].
  • Infections: The skin is home to many bacteria that can easily get into the finger via a cut, bite or other puncture. The bacteria will infect the tissues of the finger and cause entrance of fluids into the tissues that result in inflammation, swelling and other associated symptoms. Viral infections can also cause swelling of the finger in people with jobs that require exposure of the finger to body parts such as the mouth (dentists, nurses, healthcare professionals). This condition is known as herpetic whitlow [2].

Environmental

The finger is susceptible to many outside forces that can result in pain and injury.

  • Trauma: Trauma to the finger that causes pain and swelling can include simple mishaps such as jamming one’s finger on a wall or serious accidents that result in broken bones.
  • Weather: Sometimes extremely cold or hot weather can trigger swelling in people with pre-existing conditions such as Raynaud’s syndrome. Observe for any patterns in your finger swelling and tell your doctor in order to investigate an underlying condition.

Rarity: Common

Top Symptoms: recent finger injury, finger pain from an injury, swollen finger, severe finger pain

Symptoms that always occur with non-serious finger injury: recent finger injury

Symptoms that never occur with non-serious finger injury: bent or crooked finger

Urgency: Self-treatment

Middle knuckle finger dislocation

The middle knuckle is called the proximal interphalangeal (PIP) joint. A PIP joint dislocation occurs when trauma causes the bones of the finger to dislodge, resulting in a very painful and swollen joint.

Rarity: Rare

Top Symptoms: bent or crooked finger, finger dislocation at the knuckle connected to the palm, pain in the middle knuckle of the finger, finger pain from an injury, swelling of the small knuckle of the dmiddle index finger

Symptoms that always occur with middle knuckle finger dislocation: bent or crooked finger, finger dislocation at the knuckle connected to the palm

Pain In The Middle Knuckle Of The Finger Treatments and Relief

At-home treatments

If you note pain in the middle knuckle of your finger after trauma such as jamming or hitting your finger:

  • Rest, Ice and Elevate: Put an ice pack on your finger or place your finger in ice water every 15 minutes. Maintain your finger elevated and still to minimize further irritation and prevent continued fluid accumulation in your tissues.
  • Protect: If the pain and swelling persist, you can protect the affected finger from further trauma by attaching it to an adjacent finger using tape or a self-adhesive wrap. The affected finger will be less likely to move which prevents further inflammation and fluid accumulation.

When to see a doctor

If your swollen finger persists for a prolonged period of time and worsens despite not seeming related to a traumatic event, make an appointment with your doctor. Depending on the cause your doctor may initiate:

  • Antibiotics: Your doctor will prescribe antibiotics if your swollen finger is due to a bacterial infection. The antibiotics will combat the infection and allow the body to lessen its inflammatory response.
  • Rheumatologic medications: There are many different types of medications that combat rheumatologic conditions that may be causing your swollen finger. Talk to your doctor to discuss and come to an agreement about the best type of treatment.

When it is an emergency

Seek medical care immediately if:

  • Your finger appears deformed
  • You cannot straighten your finger
  • The area becomes hot and inflamed and you develop a fever
  • Swelling and pain increases significantly and persists
  • The finger becomes numb and turns white or pink

These symptoms may be related to a more serious cause such as a broken finger resulting in decreased blood flow to the finger and/or hand.

FAQs About Pain In The Middle Knuckle Of The Finger

What is a rheumatoid nodule?

A rheumatoid nodule is one of the most common skin manifestations of rheumatoid arthritis [1]. Rheumatoid arthritis is a chronic disease that causes inflammation of the joints and results in painful movement and stiffness, especially in the fingers, wrists, and ankles. Nodules are large, painful bumps that often develop in the joints of the fingers and also on the elbows, forearm, back, heel and many other areas.

What is a Heberden node?

A Heberden node is a common skin manifestation of osteoarthritis. Osteoarthritis is a chronic disease caused primarily by degeneration of joint cartilage [2,3]. A Heberden node is a hard, bony swelling that results over time due to chronic degeneration and resulting inflammation. These nodes often occur in the middle and index fingers. See this image here of nodes in someone with osteoarthritis.

What is the difference between a middle finger fracture and a middle finger dislocation?

A fracture occurs when the bones in a body part break [4,5]. A dislocation does not involve breaking bones but rather only displacement or misalignment of bones. The distinction is important as fractures and dislocations are treated differently. If you experience trauma to the finger that results in severe pain and visible deformity, make an appointment with your healthcare provider to get the appropriate diagnosis and care.

What is herpetic whitlow?

Herpetic whitlow is an infectious lesion on the finger or thumb caused by the herpes simplex virus [2]. See an image of this type of lesion here. This is often a side effect of oral herpes infection and is a common hazard in occupational settings such as dentistry and healthcare where individuals are repeatedly exposed to infected secretions.

How can I prevent infection of my middle finger?

Proper hand hygiene is the key to preventing skin infection. Wash the hands regularly with soap and water, avoid putting the hands in the mouth and make sure to cover cuts and abrasions with bandages.
