It started sometime over the past 2-3 weeks, but I've noticed that my head has started to shake/pulsate a little (in rhythm with my heartbeat). It's most noticeable when I'm lying down to sleep or resting my head against something. When lying down, it feels like a generic pattern where my head will move in tune with my heart beat three times and then vibrate slightly on one side. To get a degree of the force of the movement; I can feel my head shaking slightly when lying down, but it is very hard for someone else to notice it unless I get my heart rate up and then lie down for observation. Randomly, I also noticed today that I could see my heart beat pulsating in the skin area by my ankle bone (when lying down).

I do not believe this is a "true" PCS symptom, but I believe it is somehow related and I've noticed that this physical movement is pretty constant (albeit not really noticeable unless lying down). Additionally, I believe it is making my vertigo worst as my head is actually moving slightly due to the added pulsating pressure, which in turn gives my head the sensation that it is moving (slightly) in circles.

I was wondering if anyone else has had any experiences with this physical, pulsating sensation / vibration in the head. I'm not really sure what can be causing this. I recently had an ENT visit, which included an ENG and audiological exam (both of which came back normal, indicating a "central" vestibular issue). Additionally, I had a CTA of my head and neck and the MDs said that they both looked normal, and that there was no abnormal artery impairment/blood flow issues (in those areas of my body at least).

I'm pretty confused as to what could be causing this "new" symptom, as I haven't changed my diet (eat very clean), I have been avoiding a lot of overstimulating activities I had previously been engaging in (TV, computer time, etc.), and have actually decreased my workout intensity/times I go per week. Also, I don't believe it's stress related, as for the most part, the severity of most of my symptoms have gotten much better and overall I feel better. This pulsating in my head, vertigo, and general off-balance symptoms, however, have not really improved much.

Apologies for the scrambled post, but any similar experiences, knowledge, or advice would be appreciated.
