Pain is one of the most common reasons people seek medical care, and for many Americans, it is a daily challenge. Recent national research shows that approximately one in five adults experiences chronic pain, with rates increasing significantly as we age. Among Medicare beneficiaries living in the community, 36% reported experiencing pain most days or every day, and 31% reported back pain. For some, discomfort is temporary and manageable. For others, it can interfere with sleep, mobility, work and activities they once enjoyed.
As a neurosurgeon, I frequently encounter patients dealing with pain involving the spine and nervous system. Understanding where pain originates, how it develops and what may be contributing to it is an important part of determining an appropriate course of treatment.
Understanding Different Types of Pain
Pain is generally classified as acute or chronic, depending on how long it lasts. Acute pain typically develops suddenly, often following an injury, illness or medical procedure, and usually improves as the underlying condition heals. Chronic pain persists or recurs for more than three months. It may begin with an injury or medical condition, but in some cases, the pain continues even after the original problem has resolved.
The source of pain is equally important. Musculoskeletal pain involves muscles, bones, joints and surrounding tissues. Neuropathic pain develops when there is damage or disease affecting the nervous system and may produce burning, tingling, shooting sensations or numbness. Radicular pain occurs when a spinal nerve root becomes irritated or compressed, sometimes causing pain to travel from the neck into an arm or from the lower back into a leg.
These differences help explain why treatments that work well for one person may not be effective for another, even when their symptoms initially seem similar.
Why Pain Can Be Difficult to Diagnose
The nervous system plays a central role in how we experience pain. Specialized nerve endings detect potentially harmful stimuli and transmit signals through the nervous system to the brain, where those signals are processed. However, the relationship between physical changes in the body and the pain someone experiences is not always straightforward.
For example, two people with similar findings on an MRI may report very different symptoms. One person may have significant degenerative changes in the spine with little discomfort, while another may experience substantial pain despite relatively minor imaging findings. This is one reason physicians consider a patient's medical history, symptoms and physical examination alongside diagnostic imaging.
Understanding when pain began, where it occurs, whether it travels to other parts of the body and what activities make it better or worse can help identify potential causes. Symptoms such as weakness, numbness or changes in coordination may also provide important clues about possible nerve involvement.
Approaches to Pain Management
Pain management has evolved considerably, and there are several approaches physicians may consider depending on the underlying condition. For many musculoskeletal and spine-related conditions, conservative treatments are often considered before more invasive options.
Physical therapy and appropriately guided exercise can help improve strength, flexibility and mobility. Medications may also play a role, although the type of medication and its potential benefits and risks depend on the individual and the nature of the pain. Sleep, physical activity and stress can influence pain as well, making these factors important
considerations in a comprehensive treatment plan.
For some patients, interventional procedures, including certain types of injections, may be considered to help manage symptoms. When pain is associated with structural problems affecting the spine or nerves, surgical treatment may be appropriate in selected cases. However, many painful conditions can be managed without surgery, and treatment decisions depend on a careful evaluation of the patient's symptoms, examination findings and diagnostic results.
It's also important to recognize that managing chronic pain does not always mean eliminating it entirely. Improving mobility, reducing limitations and helping people participate more comfortably in their daily activities can all be meaningful measures of progress.
When Pain Needs Medical Attention
Occasional aches and discomfort are common, particularly as we age, but persistent, worsening or unexplained pain deserves medical attention. Pain accompanied by numbness, tingling, weakness or changes in coordination may suggest involvement of the nervous system and should be evaluated.
Certain symptoms require immediate medical attention. New loss of bladder or bowel control, numbness around the groin or rapidly progressing weakness associated with back pain may indicate a serious neurological condition. A sudden, extremely severe headache, particularly when accompanied by neurological symptoms, is another reason to seek emergency care.
Understanding the Individual
After years of practicing neurosurgery, I've learned that understanding a patient's experience is just as important as reviewing the results of an imaging study. Pain can affect nearly every aspect of someone's life, and its impact is not always apparent from a physical examination or diagnostic test.
Advances in medical technology and our understanding of the nervous system continue to improve how physicians diagnose and treat painful conditions. While there is no single solution that works for everyone, identifying the underlying cause and considering the available treatment options can help patients and their physicians make informed decisions about their care.
