I've been having slight problem with my legs being very unsteady when going down the stairs in the mornings for a rather long time, at least a year, possibly more. It's mostly been the front of my thighs.
Other than that I can't say I feel my legs trembling a lot, although I have for years had problems with standing for any period of time without my back and stomach muscles hurting, which I believe can be from trying to fight the tremors in my legs and keep me stable, although that's just a theory I've come up with on my own.
Yesterday I learned of Orthostatic Tremor and that seems to fit most of my symptoms, although I can't say I generally feel unstable. Sometimes I stumble a bit when raising, especially if I have to navigate sideways between a couch and a coffee table, but I would say my balance in general is normal.
To get to the point of my question: can the leg tremors be caused by ET since they're mostly noticable when my arms, etc. are also shaking, or is it more likely that I have OT, too? I can't remember reading or hearing about ET affecting the legs, only the upper body.
