Probably blood circulation related.

Detailed Answer:
Hello and thanks for using

I have read your question and understand your concerns.

The pulsating feeling in your case may be attributed to the abnormal circulation of the blood in the dilated part of the dissected vessel and it should be in synchronization with the heart rhythm.

This turbulence of blood may cause slight twitching of your neck too.

In rare cases, a stroke ( new one ) may be responsible for the muscles twitching, so, an evaluation by your Doctor is necessary to get a correct understanding of your condition.

Hope you found the answer helpful.

Let me know if I can assist you further.
