shaking and sweating; what could it mean?

[Guest guest]

I've been experiencing this lately:

I wake up duing my sleep and I'm shaking inside. I need to use the bathroom but

don't because I am tired and because I know that if I get out of bed to use the

bathroom I won't be able to fall asleep again.

So I remain in bed, containing my urge to pee. A few minutes later I begin to

sweat. I feel hot and swear profusely. I am so uncomfortable at this point that

I get out of bed and use the bathroom.

The shaking has stopped amd the sweating is slowly easing off.

Could this be my body's attempt at balancing electrolytes?

My magnesium is low. 1.9

My potassium is 3.8

My sodium is 140
