The body is like a supercomputer. The brain sends electrical impulses through nerves to keep your heart beating, lungs breathing, and gut digesting food. They activate muscles so we can move, blink our eyes, and speak.
Nerves don’t just work one way, however. Each sends constant feedback to the brain so the brain can make adjustments where necessary. Nerves transmit signals about encounters with light, color, sound, temperature, pressure, friction, and injury.
The nerves travel from the base of the skull down through the spinal column, branching out to your organs, muscles, and skin until everything is connected. Nerves traveling away from the spine are called peripheral nerves. Neuropathy is nerve damage. Peripheral neuropathy is damage to the nerves radiating out to the extremities, and damage is often noticed in the feet first.
What Causes Nerve Damage?
Unfortunately, there are many causes of neuropathy. The key to figuring out which burning pain treatment you need is assessing the root cause of the damage.
Nerves need oxygen, nutrients, unrestricted range of motion, and structural stability to thrive. You mess with any element, and you get nerve damage. Damaged nerves can’t signal normally, and signals get interpreted as burning feet, pain, tingling, numbness, hypersensitivity, or perceived temperature changes. Causes include:
- Diabetes: Elevated blood glucose levels damage blood vessels that feed nerves nutrients and oxygen.
- Nicotine: Nicotine constricts blood vessels, limiting blood flow, oxygen, and nutrients.
- Myelin deterioration: Myelin is the insulating sheath surrounding nerves. Toxins and autoimmune disorders like Lupus or Guillain-Barré syndrome can cause the myelin to deteriorate, leaving nerves exposed.
- Trauma: Trauma to any of the nerves can cause temporary or permanent damage.
- Alcohol: Drinking excess alcohol leads to vitamin B deficiencies. Vitamin B is essential for healthy myelin sheaths. Excessive alcohol can also damage the small blood vessels, feeding and oxygenating the nerves.
- Nutritional Deficiencies: Vitamin B, copper, calcium, zinc, magnesium, and other nutrients are necessary for nerve health and functionality.
- Genetics: Some genetic conditions cause nerve deterioration.
- Infectious Disease: Infectious diseases like Lyme and shingles can also cause nerve damage.
- Chemotherapy: While chemotherapy kills cancer cells, it does damage to healthy cells also. A common side effect is peripheral neuropathy.
