Occasional tingling after sitting or sleeping in an awkward position is usually harmless.
Persistent or recurring tingling without an obvious explanation deserves more attention.
## 2. Numbness in the Hands or Feet
Nerve changes can reduce normal sensation.
You may notice:
* difficulty feeling temperature
* reduced sensitivity to touch
* a “dead” feeling in the toes or fingers
* difficulty noticing small injuries
Numbness in the feet is particularly important because a person may develop cuts, blisters, or pressure injuries without realizing it.
This can be especially concerning for people with diabetes.
## 3. Burning Pain
Some nerve problems cause burning rather than numbness.
The sensation may feel like:
* hot skin
* burning feet
* internal heat
* stinging
* painful sensitivity
Symptoms can become more noticeable at night when you are resting.
Burning pain in both feet is often associated with peripheral nerve problems, but many other conditions can produce similar symptoms.
