Hi, If the tingling is episodic lasting for seconds to minutes, then, the most likely cause is sensory seizures. If the tingling is constant lasting for more than 24 hours, then they are suggestive of a pathology in brain. At this age, demyelinating disorder is the most common. If you are so troubled, ignore and live. However, if they are bothering you, it is better to undergo MRI brain and spine with contrast and lumbar puncture. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Sudhir Kumar, Neurologist
