• Medical conditions: Such as arthritis, fibromyalgia, endometriosis, and migraines.
• Nerve damage: Neuropathic pain can result from nerve injury or damage.
• Surgeries: Post-surgical pain can become chronic in some cases.
• Inflammatory conditions: Diseases like rheumatoid arthritis can lead to chronic pain.

Diagnosis

• Medical history and physical examination: Comprehensive assessment by a healthcare provider.
• Imaging tests: Such as X-rays, MRI, or CT scans to identify underlying issues.
