Tingling

Transient

The most common everyday cause is temporary restriction of nerve impulses to an area of nerves, commonly caused by leaning or resting on parts of the body such as the legs (often followed by a pins and needles tingling sensation). Reactive hyperaemia, which occurs when blood flow is restored after a period of ischemia, may be accompanied by paresthesia too, e.g., when patients with Raynaud's disease rewarm after a cold episode. Other causes include conditions such as hyperventilation syndrome and panic attacks, in which paresthesias of the mouth, hands, and feet are common, transient symptoms. A cold sore outside the mouth (not a canker sore inside the mouth) can be preceded by tingling due to activity of the causative herpes simplex virus. The varicella zoster virus, which causes shingles, also notably may cause recurring pain and tingling in skin or tissue along the distribution path of that nerve (most commonly in the skin, along a dermatome pattern, but sometimes feeling like a headache, chest or abdominal pain, or pelvic pain).
