  • Inflammatory/autoimmune: the body's immune response producing pins and needles as a bystander effect
  • Metabolic: disorders of thyroid, adrenal, or blood glucose regulation
  • Structural/mechanical: nerve compression, joint damage, or organ enlargement
  • Underlying conditions: Peripheral Neuropathy are among the leading identifiable causes

Red Flags — When to Act

  • Unintentional weight loss accompanying pins and needles (possible malignancy or metabolic disease)
  • Night sweats, fever, and pins and needles persisting >2 weeks
  • New pins and needles in someone with a known cancer, immunosuppression, or recent surgery
  • Rapid progression or change in the character of long-standing pins and needles
  • Family history of serious hereditary conditions presenting with pins and needles
