Chronic Pain Diagnosis: What Should Be Ruled Out

Chronic pain—pain that lasts longer than three months—affects millions of people worldwide. If you’re asking “how to get a diagnosis for chronic pain,” it’s crucial to understand that chronic pain isn’t a single disease but a symptom with many possible causes. A thorough evaluation helps rule out serious conditions and guides effective treatment. Below, we outline key steps and conditions your healthcare team should consider.

1. Start with a Detailed History and Physical Exam

A comprehensive history and exam help narrow down potential causes:

• Onset and duration
  • When did pain start?
  • Was there an injury or illness?
• Location and pattern
  • Is it localized or widespread?
  • Does it come and go or stay constant?
• Quality and intensity
  • Sharp, dull, burning, throbbing?
  • Pain scale: 0 (none) to 10 (worst)
• Aggravating and relieving factors
• Impact on daily life
  • Sleep, mood, appetite, mobility
• Past medical history
  • Previous surgeries, infections, autoimmune disease
• Medications and supplements
• Family history of chronic conditions

A hands-on physical exam checks for tenderness, range of motion, neurological signs (numbness, weakness), and vascular changes (poor pulses, swelling).

2. Rule Out Red-Flag Conditions

Red flags are signs that point toward potentially serious or life-threatening causes. If any of these are present, urgent evaluation is needed:

• Unexplained weight loss or fever
• History of cancer
• Night pain that prevents sleep
• Severe, unrelenting pain not relieved by rest or medication
• Neurological deficits (e.g., sudden numbness, weakness, bladder/bowel dysfunction)
• Signs of infection (redness, warmth, fever)
• History of intravenous drug use or immunosuppression

If red flags arise, your doctor may order urgent labs (CBC, ESR/CRP), imaging (X-ray, MRI, CT), or refer you to a specialist.

3. Laboratory Tests to Exclude Systemic Disease

Blood and urine tests help identify or rule out systemic illnesses:

• Complete blood count (CBC)
  • Anemia, infection
• Inflammatory markers (ESR, CRP)
  • Rheumatoid arthritis, lupus, vasculitis
• Metabolic panel (electrolytes, kidney/liver function)
• Thyroid-stimulating hormone (TSH)
  • Hypo- or hyperthyroidism
• Blood glucose or HbA1c
  • Diabetes, diabetic neuropathy
• Rheumatologic panels (ANA, RF, anti-CCP)
• Vitamin D, B12, folate levels
• Urinalysis
  • Kidney stones, infection

Abnormal results guide further work-up or specialist referral.

4. Imaging Studies to Identify Structural Issues

Imaging can reveal fractures, tumors, degenerative changes, or nerve compression:

• X-ray
  • Fractures, arthritis, bone tumors
• MRI
  • Soft tissue pathology, disc herniation, spinal stenosis
• CT scan
  • Complex bone fractures, detailed bone anatomy
• Ultrasound
  • Tendon tears, soft-tissue masses, joint effusions
• Bone scan
  • Occult fractures, metastatic disease, infection

Not every patient needs advanced imaging—your doctor will order studies based on history, exam, and red-flag findings.

5. Neuropathic vs. Nociceptive Pain

Understanding pain type guides treatment:

• Nociceptive pain
  • Result of tissue damage (e.g., arthritis, muscle strain)
  • Usually responds to NSAIDs, physical therapy
• Neuropathic pain
  • Nerve injury or dysfunction (e.g., diabetic neuropathy, shingles)
  • Often described as burning, tingling, electric shocks
  • May require anticonvulsants, antidepressants, topical agents

Screening tools (e.g., DN4 questionnaire) help identify neuropathic components.

6. Rule Out Inflammatory and Autoimmune Conditions

Chronic inflammatory diseases can cause persistent pain:

• Rheumatoid arthritis and other inflammatory arthropathies
• Systemic lupus erythematosus (SLE)
• Ankylosing spondylitis
• Psoriatic arthritis
• Vasculitis

Look for joint swelling, morning stiffness longer than 30 minutes, rash, and multi-system involvement.

7. Consider Visceral and Referred Pain

Sometimes the source isn’t where you feel the pain:

• Gallbladder disease (right shoulder or back pain)
• Pancreatitis (upper back pain)
• Peptic ulcer disease (mid-back pain)
• Kidney stones (flank pain radiating to groin)
• Endometriosis (pelvic pain radiating to back)

Lab tests, ultrasound, CT, endoscopy, or laparoscopy may be needed.

8. Evaluate for Myofascial and Musculoskeletal Syndromes

Muscle and connective tissue disorders often cause chronic pain:

• Myofascial pain syndrome
• Fibromyalgia
• Tendinopathies, bursitis
• Overuse injuries (e.g., carpal tunnel syndrome)

Physical exam findings (trigger points, tender bands), along with patient history, guide diagnosis.

9. Assess Psychological and Social Factors

Pain is influenced by mood, stress, and life context:

• Screen for anxiety, depression, PTSD
• Identify stressors, family or work issues
• Consider referral to a pain psychologist or counselor

Cognitive-behavioral therapy (CBT) and mindfulness can be highly effective when combined with medical treatment.

10. Using Online Tools to Prepare for Your Appointment

Before seeing your doctor, gather information and symptoms. You might also try a free, online symptom check, using the doctor approved Ubie Symptom Checker to help clarify your concerns and generate a preliminary report to discuss with your care team.

Putting It All Together: Steps to Get a Diagnosis

1. Schedule an appointment with your primary care provider (PCP).
2. Keep a pain diary: track intensity, triggers, relief measures.
3. Share your history and diary during the visit.
4. Undergo recommended labs and imaging.
5. Follow up on test results; ask questions about next steps.
6. Seek referrals to specialists (rheumatologist, neurologist, pain management) as needed.
7. Explore multidisciplinary care: physical therapy, psychology, occupational therapy.

When to Seek Immediate Medical Attention

Contact emergency services or go to the nearest emergency department if you experience:

• Sudden, severe pain with chest tightness or shortness of breath
• Weakness or numbness in face, arm, or leg, especially on one side
• Loss of bladder or bowel control
• Fever with back pain
• Signs of serious infection (rapid heartbeat, worsening redness/swelling)

Final Thoughts

Getting a clear diagnosis for chronic pain can be a journey. Your healthcare team’s goal is to rule out life-threatening and reversible conditions, identify pain drivers, and create a tailored treatment plan. Patience and open communication are key.

Always speak to a doctor about any pain that is severe, sudden, or associated with other worrying symptoms. Early evaluation can prevent complications and improve your quality of life.
