Thank you for sharing

I think mine is vaccine related. Developed essential tremor with that internal vibration. Tried Beta Blocker, made me so tired all the time. Have been off for about 3 months. tremors are better. Vibration happens on and off. Terrible tennitis which I had before this. Was diagnosed in April with ET and not happy. If I had covid I never knew. Tested before traveling but always negative. Working with Physical Therapist who attributes ET and vibration to vaccine as well.

I also have these vibrations full body and it's unsettling. Anything helped u?

Hi , I can't tell you how relieved I am to have just found your post!
I started having the same distressing internal tremors as you following my third (booster) Covid vaccine. It's worse when I first wake up but can also occur during the day.
My GP prescribed beta blockers which I took for five months - the tremors didn't abate so I discontinued them (I also experienced hair loss as a side effect of the BBs)
My short term memory has deteriorated and I get dry scratchy eyes.
In addition, I had all three covid jabs in my left arm and now have trouble with my shoulder joint.
Yes , I know I'm aging like everyone else but I've gone from being a fit and active, reasonably intelligent woman , to one who is always fatigued and plagued by these awful tremors inside my body. I constantly hold my hands out in front of me because I can't believe I'm not physically shaking on the outside when the tremors are at their worst.
Whilst I realise that health care professionals argue that the benefits of Covid vaccine outweigh the risks; I really hope and pray that more in depth research will be carried out to investigate the side effects that people like us are suffering.
Thank you for sharing and I really hope we can both feel better in the near future.
Ps: I didn't contract Covid either (did numerous tests).

Wondering how this is going for you? I now have long vaccine injury and two of my remaining symptoms are tinitus and internal vibrations. Are they still persistent for you?

I'm experiencing very similar symptoms. Please share if anyone found any treatment options.
I had severe COVID in Jan 2021. But I recovered fully from it. No weird symptoms after recovering from COVID. 7 months later, in July 2021 I received my 2 COVID-shots (Moderna). 2 weeks after the COVID shots I woke up with severe internal vibrations. And they have not gone away since then. It is a daily thing. When the internal vibrations started in Aug 2021. They are concentrated in my neck, back/shoulders and arms. I spent thousands of dollars in copayments and deductibles for MRIs. MRAs, CT Scan and consulting with neurologists, but no help. I also saw a physical medicine doctor who put me on Gabapentin. it helped a bit, but I was worried that I will get hooked on Gabapentin for life.
A few months ago, a found a doctor who prescribed low dose of naltrexone (started with 2 mg and slowly increased to 6 mg daily before going to bed). I stopped gabapentin once I started LDN. LDN has relieved day time internal vibrations. Now, I only feel it after going to bed at night and when I wake up in the morning. They go away after 10/15 minutes once I start walking around.
I also noticed that light exercise helps to calm down the vibrations. I'm also practicing deep breathing/meditation, long walks, etc.
BTW: I also have severe tinnitus (high pitch sound) in my right ear. Again, no cure for it.
