Tingling, numbness, and nerve pain have biological causes that go beyond the nervous system itself.
Peripheral neuropathy, characterized by tingling, numbness, burning, or pain in the extremities, is typically approached by conventional medicine as a nerve problem to be managed with pain medication or nerve-blocking drugs. But peripheral neuropathy is almost always a downstream symptom reflecting underlying biological disruption elsewhere in the body.
Common root cause contributors include heavy metal toxicity (particularly mercury and lead), tick-borne infections including Lyme disease and Bartonella, mold toxicity, nutritional deficiencies (especially B vitamins), and blood sugar dysregulation. Addressing these underlying factors, rather than managing the nerve symptoms in isolation, is the approach that leads to lasting relief.
