Key takeaways

- High blood sugar is a leading cause of nerve damage.
- Vitamin B12 is vital for nerves.
- Pressure on nerves causes tingling.

Your nervous system is your body's communication network. When nerves are irritated or damaged, you may feel tingling, burning, numbness or discomfort.
How nerves work
Sensory nerves
Carry information about touch, temperature and pain from skin and muscles to the brain.
Motor nerves
Send signals from the brain to muscles so you can move.
Autonomic nerves
Control automatic functions such as heart rate, digestion and blood pressure.
Common causes of nerve discomfort
| Cause | What helps |
|---|---|
| High blood sugar | Blood sugar management with your doctor |
| Low vitamin B12 | Testing and diet or supplements as advised |
| Nerve compression | Posture, ergonomics, physiotherapy |
| Alcohol | Limit or avoid |
| Inactivity | Regular gentle exercise |
Supporting your nerves every day
Eat a balanced diet with B vitamins, keep blood sugar steady, walk daily, stretch, protect your feet and sleep well. Some people add a botanical supplement such as NerveCalm, with corydalis, California poppy, passion flower, marshmallow root and opuntia, to support nerve health, comfort and relaxation alongside medical care.
