What is Chronic Pain?
Constant pain is defined as any pain lasting longer than 3 months. It differs
from acute pain, which serves an important protective function by warning us of
potential tissue damage. Constant pain persists weeks or even years after an
initial injury has healed or a causal disease has been treated. Some key points
about constant pain include:
- It has no clear biological purpose and does not directly relate to tissue
damage. Rather, it is a disease state in itself.
- Its underlying causes can be physical/biological as well as psychological and
social factors. Not all constant pain has a definable underlying injury or
pathology.
- It often involves changes in the central nervous system that make pain
signals continue even after an initial cause has resolved. Nerve cells become
more sensitive and transmit impulses more readily.
- Sufferers commonly experience decreased functioning and decreased quality of
life due to severe, uncontrolled Chronic
Pain
that interferes with daily activities and responsibilities.
- There is no definitive diagnostic test for constant pain and diagnosis is
usually based on comprehensive patient history, physical exam, and diagnostic
testing to rule out potential causes.
Common types and causes of Chronic Pain
There are many different types of constant pain according to the cause and
location of symptoms. Some of the most common include:
- Low back pain - A leading cause of disability worldwide, often triggered or
worsened by injuries, arthritis, muscle strain, or poorly aligned spine.
- Osteoarthritis - Degeneration of joints from "wear and tear" over
decades can cause persistent pain and stiffness, especially in hips, knees.
- Fibromyalgia - Characterized by widespread musculoskeletal pain often
accompanied by fatigue, cognitive issues, and sensitization to touch and
multiple tender points.
- Neuropathic pain - Caused by damage or disease affecting the somatosensory
nervous system. Includes post-herpetic neuralgia, painful diabetic neuropathy.
- Migraine/headache disorders - Frequent, severe headaches not directly related
to underlying injury or pathology.
- Cancer pain - As a direct result of tumor growth or indirectly from
treatments like surgery, chemotherapy.
Assessing and diagnosing constant pain
Diagnosing constant pain can be challenging due to its subjective nature and
lack of definitive tests. A comprehensive evaluation aims to:
- Characterize pain location, type, triggers, and other associated symptoms.
- Identify possible underlying physical/medical causes via imaging, labs,
specialty exams.
- Assess impact on daily activities and quality of life using pain scales or
questionnaires.
- Screen for psychological factors like stress, anxiety or past trauma that
could contribute.
- Check for "red flags" like weight loss, fever indicating more
serious underlying condition.
- Rule out substance abuse issues complicating diagnosis or treatment.
Developing an effective treatment plan
If underlying causes are identified, addressing them directly is the priority.
However, for most constant pain, the focus shifts to managing rather than
curing since complete relief is often not possible. Multimodal treatment aims
at:
- Medications like analgesics, antidepressants, anticonvulsants, and
corticosteroids depending on cause.
- Physical therapy and exercise to improve strength, mobility and conditioning
to help cope.
- Lifestyle modifications around diet, stress relief, smoking cessation, weight
loss if relevant.
- Complementary therapies like acupuncture, yoga, massage, and meditation with
some supportive evidence.
- Cognitive behavioral therapy to identify coping strategies, reframe negative
thought patterns.
- In some cases interventional procedures such as nerve blocks or implantable
spinal cord stimulators may help.
- Ruling out underlying psychological issues potentially exacerbating pain.
Treating these directly with counseling or care.
The challenges of treating constant pain
Despite best efforts, attaining adequate pain control remains elusive for many
patients. Barriers to effective management include:
- Limited understanding of constant pain mechanisms and resistant nature makes
it difficult to cure. Managing, not eliminating pain is often goal.
- Inadequate physician training in constant pain assessment and treatment,
especially non-pharmacological options.
- Patient anxieties, fears, depression negatively impacting self-efficacy and
engagement in comprehensive plans.
- Stigma that constant pain is "all in the head" or due to substance
abuse vs legitimate disease state.
- Risk of dependence or misuse with prescription opioids requiring careful
risk-benefit analysis.
- Lack of treatment coordination, follow up, non-medical support systems to
address biopsychosocial aspects.
- Difficulty accessing specialists like pain psychologists, inadequately
covered alternative therapies.
