Tingling in the feet - Definition

Ask a question


Paresthesia is described as a tingling sensation of varying duration and intensity. It may affect the feet or a larger area of the leg. In most cases, the causes of tingling are not dangerous, such as exposure to cold, or a nerve irritation due to prolonged compression of an area of the limb. However, the tingling can also be related to more serious problems, such as a worsening of diabetes (i.e., diabetic neuropathy) or a neurological disease such as multiple sclerosis or Guillain Barré syndrome.
