The tingling and palpitations that have been spreading throughout the body can be caused by several conditions. Here are some possibilities based on the search results:

  • Episodic Neurologic Symptoms: Patients with this condition usually complain of severe apprehension, dizziness, chest discomfort, palpitations, or fear of “losing control.” The onset is usually under age 40[1].

  • Heart Attack or Panic Attack: Both conditions can cause chest pain, shortness of breath, dizziness, sweating, passing out, tingling, or a sensation of impending doom. These shared symptoms of heart and panic attack may also be caused by other serious conditions such as blood clots, lung infection or collapse, or tear in the large vessels of the chest for patients with certain pre-existing risk factors[2].

  • Atrial Fibrillation: The most obvious symptom of this condition is heart palpitations, where the heart feels like it’s pounding, fluttering, or beating irregularly, often for a few seconds or possibly a few minutes. Other symptoms include tiredness, feeling lethargic, chest pain, dizziness, and shortness of breath[3][6].

  • Peripheral Neuropathy: Symptoms of this condition include numbness and tingling in the feet or hands, burning, stabbing or shooting pain in affected areas, loss of balance and coordination, and muscle weakness, especially in the feet. These symptoms are usually constant but may come and go[4].

It’s important to see a doctor if you experience any of these symptoms to determine the underlying cause and receive appropriate treatment.
