Why Does Chronic Pain Develop?

Chronic pain is pain that lasts longer than six months, and, if untreated, it can last day and night. Acute pain signals an injury, and it typically fades within a few weeks. Chronic pain continues even after the original injury has healed. Here are four root causes behind long-lasting discomfort:

Neuropathic Pain

Neuropathic pain develops when the nerves themselves become damaged or diseased. It feels different from muscle or joint pain, which can manifest in specific ways. Diabetes is a leading cause of neuropathic pain in the United States. Neuropathic pain can present itself in a variety of ways, and you may experience one or more of the following sensations:

• Burning or stabbing pain
• Tingling or “pins and needles”
• Numbing sensation in the hands or feet
• Having pain from light touch, such as clothing or bedsheets

Neuropathic pain can significantly impact daily life, making even routine activities like walking or wearing socks uncomfortable. It typically arises from conditions such as diabetes, multiple sclerosis, or chemotherapy, but treatment options are available. While managing this type of pain can be challenging, early intervention and a personalized approach can help improve quality of life.

Nerve-related Issues

Your nerves carry signals between your body and brain, and they help you sense pain. When nerves become damaged or irritated, they may send pain signals without a clear cause. This problem sits at the center of many chronic pain conditions. Damage may occur at any point along the nerve pathway.

Nerve damage can start with conditions that affect blood flow or put pressure on nerves. Diabetes, shingles, and spinal disc problems are typical causes. Surgery or accidents may also harm nerves, and some medications have similar effects. After an infection clears, some people develop nerve pain.

Over time, the nervous system itself may change. When pain signals repeat for weeks, nerves become more sensitive to them. The brain starts to amplify these signals, and doctors call this central sensitization. The pain may continue for months or years.

Complex Regional Pain Syndrome

Complex regional pain syndrome (CRPS) typically affects one arm or leg, and it often follows an injury. The pain feels far more severe than the original injury. CRPS may develop when the nervous and immune systems respond abnormally to damage.

CRPS also changes the affected skin. The area may swell or change color, and its temperature may differ from the other side. Some people notice changes in hair and nail growth as the condition continues. As symptoms vary from person to person, they may shift over several months.

Myofascial Pain Syndrome

Myofascial pain syndrome affects the muscles and the fascia, which is the thin tissue around them. The pain centers on trigger points. These points are tight knots in the muscle, and pressing on them may cause pain in another area. Typical triggers include:

• Repetitive motions at work or during exercise
• Poor posture over long periods
• Sudden muscle injuries or strain
• Ongoing muscle tension

Find Treatment for Chronic Pain

Chronic pain has many possible sources, so before a provider recommends treatment, they review your history, symptoms, and exam results. Some causes involve nerves, and others start in muscle or soft tissue. A clear diagnosis guides each next step, depending on the specific source of your pain. If your pain has lasted longer than six months, schedule a consultation with a pain management team.
