I've experienced mild shakiness periodically in the past, commonly after lifting weights and also more noticeable when nervous, but in the past few weeks I feel as if my body has gone haywire.
Symptoms I've experienced:
-Hand and arm tremors
-Leg tremors
-Thumb tremors in particular and some twitches
-Fasciculations all over body (shoulder, eyebrows, calves, arms, etc..)
-Increased anxiety (probably as a result of all this but my body just feels physically on edge, not a pleasant feeling)
-Difficulty speaking (out of breath, voice feels strained and feel as if I stutter up on words sometimes though no one else notices, might be related to chronic sinus congestion + strained voice due to anxiety)
-Occasional numbness and tingling in arms/legs
-Rigidity/jerky movements especially when moving body part slow or controlled (neck, wrists, legs, arms)
However, the strangest thing to me seems to be the leg tremors which have just popped up. If I hold my leg in the air while laying down for example or lift it up from my chair for 5-10 seconds my quad will start to jerk a bit. It starts off subtle but can get pretty pronounced if I continue holding it 15-20+ seconds. I've never noticed this happen before the past few weeks.
The other thing I'd like to note is that the tremors seem somewhat inconsistent. After weeks of this, yesterday I experienced only very light tremors and today has been a little more shaky but still not bad. It seems to fluctuate a lot throughout the day. I've read about ET but am kind of wondering since leg tremors seem very uncommon with it and because of sudden onset and because they range in severity quite a bit.
One last thing to mention is I had two weird episodes before this. Both of them just involved a focused twitch of one body part. One was my right lip for about a week in December. The other involved my right thumb (and eventually my left as well) for about 3 in February. Both of these were a very focused twitch to that one body part that relented on for weeks. Luckily they both subsided and have had only very minor symptoms of either this time, but thought that was interesting to note.
I'm really hoping this could be some kind of vitamin deficiency. I've been taking sublingual b12 and methylfolate for about a week now and it seems to help the symptoms at times, but doesn't last. I've also upped my vitamin D and been more consistent about taking it as well as magnesium. I'd like to think this might be a curable condition since it had such an acute onset. The tremors got worse right as all this twitching and random tingling started so it seems connected. I've had mild shakiness like I said in the past but only in my hands and very mild, never noticed it once outside of anxiety inducing situations (I have rather bad anxiety) or after an intense workout which I viewed as pretty normal.
