Shaking muscles help

[NewSoul]

Hello everyone.  I'm hoping one of you can help me with my problem.

It first started earlier this year when I was walking down the stairs one morning.  I noticed that my legs were really shaky when I was walking down the stairs.  Have you ever exercised your muscles until the point of them shaking?  That is what it's like, but I had just woken up and had not been doing any sort of strenuous activity.  It's a bit unusual for me because I am a fairly active 17-year-old and my leg muscles are not weak.  Oddly, I would only feel it when slowly walking down the stairs and not notice it walking up the stairs.  Also, they only shake when they are in the PROCESS of bending.

Then, I started noticing some shaking in my shoulder area when moving my arms down.  They don't shake if they are being held in a steady position or if I am moving them up.  Another area that I began to notice is the shaking of my lower back as I bend over.  Sometimes my fingers shake as well.  Again, none of my muscles shake when being held in a steady position.  They only shake in the process of moving in certain ways.

At first, I thought that I was just imagining things.  However, one day my family went out to eat and we ordered some chips and dip.  I had to reach across the table to reach the dip, and I moved slowly so as not to spill anything.  As I brought the chip up to my mouth, my brother started laughing because he noticed my arm was shaking.  I was kind of surprised that I wasn't imagining the shaking.

Anyway, at first, I thought that this shaking would only happen in the morning.  I take dance classes in the mornings and usually had a hard time with shaking in the beginning of the class, but later in the day I would be fine.  However, in one of my evening classes the other night, I had a difficult time with the shaking arms and legs.  It's not noticeable to others because I am constantly moving, but it's difficult for me to balance when I shake like this.  I know the shaking is not due to hypoglycemia either, as I had eaten before class.

I would really like to know the cause of this issue.  Like I said before, I've ruled out hypoglycemia.  Also, stress does not seem to be a factor as I have not been stressed lately.  Some days are worse than others, but it makes dancing more difficult so I would like to resolve it.  Other than dance, it's not really a concern.  My little brother is the only one who noticed it that one time.

Could I be dehydrated and not know it?  Any other ideas?

Thanks and I really appreciate it.

I would recommend consulting a Neurologist for a work-up and getting imaging of your spine.
