What are the common causes of paresthesia all over the body?

Paresthesia is the feeling of tingling, numbness, or pins and needles. This can happen when nerves are not working as they should.

One common cause is neuropathy, where nerves get damaged or irritated. For instance, high blood sugar in diabetes can hurt the nerves—a condition called diabetic peripheral neuropathy. Sometimes, an injury or pressure on nerves (like a pinched nerve) can lead to these sensations too. In some people, a lack of important vitamins, such as vitamin B12, can make the nerves weak and cause tingling feelings.

Other health conditions that affect nerves might also be the culprit. These nerve issues can send mixed signals to your brain, so you feel a tingling all over your body. While occasional, mild tingling can be harmless, persistent or worsening sensations might mean that there is an underlying problem. If you are experiencing ongoing symptoms, you can start by taking a free symptom checker assessment to help identify potential causes and determine whether you should consult with a healthcare provider who can recommend ways to manage or treat the condition.
