What Is Somatic Pain?

A type of pain we have all experienced at some point in our lives.

If you cut your skin, the pain you experience is somatic pain. You also experience somatic pain if you stretch a muscle too far, exercise for a long period of time, or fall down onto the ground and hurt yourself. 

Definition of Somatic Pain

Somatic pain is a type of nociceptive pain that is also referred to as skin pain, tissue pain, or muscle pain. Unlike visceral pain (another type of nociceptive pain that arises from internal organs), the nerves that detect somatic pain are located in the skin and deep tissues.

These specialized sensory nerves, called nociceptors, pick up sensations related to temperature, vibration and swelling in the skin, joints and muscles—basically any painful stimuli. When they detect some kind of tissue damage, nociceptors then send impulses to the brain, which is how you feel or experience pain.

Somatic pain can be either superficial or deep.

Superficial Somatic Pain

Superficial pain arises from nociceptive receptors in the skin and mucous membranes. For example, if you cut your lip, this pain is called superficial somatic pain. Superficial somatic pain is the type of pain that happens with common everyday injuries and is characterized as pricking, sharp, burning or throbbing pain.

Deep Somatic Pain

Deep somatic pain originates from structures deeper within your body, such as within your joints, bones, tendons, and muscles. Like visceral pain, deep somatic pain is usually dull and aching.

Deep somatic pain can either be experienced locally or more generally depending on the degree of trauma. For example, if you bump your knee, then the pain that you experience is localized to your knee. However, if you break your kneecap (called your patella) you likely experience pain in your whole leg.

Treatment of Somatic Pain

Depending on the severity and extent of the injury or trauma, as well as the quality of pain a person is experiencing (for example spasming versus throbbing ), somatic pain is treated differently.

Most minor cases of somatic pain respond well to over-the-counter medications such as Tylenol (acetaminophen) or NSAIDs like Aleve (naproxen) or Motrin (ibuprofen). A big difference between Tylenol and NSAIDs is that Tylenol offers no anti-inflammatory effects. So, Tylenol won't help with associated swelling. That being said, some people cannot take NSAIDs due to underlying health conditions like a history of gastrointestinal bleeding, kidney disease, or heart disease.

This is why it is important to always consult your doctor before taking any medication, even those available over-the-counter.

With deep somatic pain, or musculoskeletal pain, muscle relaxants like Baclofen or Flexeril (cyclobenzaprine) may provide relief. Opioids, or medications like oxycodone and hydrocodone, are best reserved for severe pain that is not relieved with Tylenol or NSAIDs alone.

Please keep in mind that opiods carry a great risk of substance misuse and dependence. This is why opioids are typically prescribed for short periods of time.

Depending on the pain, your doctor may also recommend other therapies like a heating pad or cold pack on the painful area, or even activities like physical therapy, massage, or relaxation. 

A Word From Verywell

The good news about somatic pain is that it usually fades once the underlying injury or insult heals. However, somatic pain that lasts longer than expected (more than 3 months) can become chronic pain, which requires a more rigorous treatment plan.
