This sensation can occur due to a variety of reasons such as nerve damage, medication, or a medical condition. There are several synonyms for the word paresthesias, such as pins and needles, tingling, numbness, burning sensation, and crawling sensation. Each of these terms can be used to describe a slightly different sensation or feeling, but ultimately they all describe a similar condition.
