Internal vibration

Theoddora having seen your post on another thread about the recent death of your husband, so sorry for your loss surely one of life's most traumatic events and as such that could have well exacerbated this condition in your case, quite possibly as other have pointed out anxiety could be a contributing factor.

I often think, if only some things we experience had a name then we wouldn't have to explain what I'm sure many of us feel are vague symptoms, variously described here as "buzzing", "shuddering", "vibrations" "fizzing" "internal engine running" "an inner bee" but the fact that quite a few have come to this forum to outline these weird and unpleasant sensations, certainly makes me feel "well not just me then"

I do feel mine present when I'm tired which is often a self perpetuating cycle, since the menopause, poor sleep quality, over tired and never able to attain that elusive good night's sleep. It's a lucky woman imo who passes through the menopause unaffected.

I gave up caffeine and after a week or so the feeling disappeared. Giving up caffeine was difficult in itself gave me headache for a few days but well worth it .

I sometimes have this too. No medical reason has been found for it and treatment for hyperthyroidism has had no effect on it.

As far as I have been able to work out, it occurs for me, either when I have physically done too much hard work, such as digging the garden, or is an allergic reaction to certain things liked smoked fish.

So others who have seen their doctors about it and not been diagnosed with some condition that explains it, or given medicine that helps, might like me want either to steer clear of certain foodstuffs or do less physically hard work.

I sometimes get something fitting this description, and on a few occasions recently it has coincided with my having restless legs. I have wondered if the two are linked.

I used to get this feeling for years It was very disturbing
I noticed it was always just before a large earthquake happened somewhere on the planet
As an empath I figured I was picking up on Earths vibration
One night I said out load “I’m choosing not to surrogate Earths disturbance anymore”. It stopped & never came back
Bit whacky answer I know but it worked for me
