Hello and welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
Pulsations in your neck can be due to:
1) In lean people pulsation of blood vessels are easily seen in excited states, it is normal.
2) Pulsations can be due to other underlying diseases, but in your case you have not mentioned about any other symptoms apart from pulsation in neck.
Look out for other symptoms like breathlessness, increased
fatigue,
excessive sweating on palms,
cold and heat intolerance, difficulty in swallowing, palpitations, irregular menses (females), loss or gain of weight significantly. If you feel any of the above mentioned symptoms are significantly noticed by you, then you have to be evaluated further. If not, then you are alright and need not worry at all.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Suhas Chauhan
