Throbbing Pulse - Inner Ear problem?

Dear doctors, pls provide guidance on below issue Had positional vertigo few months back (vertigo only when I slept towards by right side). Did epleys maneuver (4 times), I panicked during excercise and had few vomiting episodes but vertigo stopped. However, Following day onwards I started throbbing pulse throughout, mostly behind head and shoulder and I feel it more when I lay down for sleep. Neurologist ruled any issue with head after MRI. Cardiologist ruled out heart issues. BP normal. Would this thorbbing pulse is because of any inner ear issue or infection? Has anyone treated or heard of this before? Throbbing pulse is like feeling your pulse very hard when I sit or sleep. Especially behind my head and shoulder
