Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. If the symptoms of tingling sensation go longer than 2-3 days and they do not seem to be getting better he needs to be seen by a doctor. Generally anxiety might cause strange sensation but they are mostly not continuous, they come and go so if his tingling sensation is for not coming and going or is for more than 3 days or is getting any worse, or if he has other neurological symptoms like weaknesses, than he needs to see a doctor. Hope I have answered your query. Let me know if I can assist you further.
