I'm glad that you shared this interesting information, @slynnb. I take it that intracellular magnesium test must be different than a regular magnesium test? What type of doctor would be most likely to run this type of test?

Did you come upon this information from personal experience or by reading about it?

To be more specific ( and please excuse typos, i'm in a big hurry due to work) - the intracellular test is a red blood cell (RBC) test which measures the level of magnesium found inside the red blood cells NOTthe magneisum just floating in the blood serum. Symptoms of low levels of magnesium in red blood cells include heart palpitations, muscle cramps, muscle tremors and twitches and more.

I have shakiness that has occurred ever since I have taken the drug Gabatril. I wake up in the morning and my right hand shakes incessantly (phone can fly out of hand) . It started on the drug. The top of my body has a tendency to shake after a seizure recently when I am lying down (all seizures are usually in bed.If I am sitting body and my arms feel shaky too. My hands shake that my hand writing is like an person's at any time of the day. My neurologist has seen both arms shake and said nothing. I want to get rid of this shakiness. Slynnb@slynnb you say the source of the shakiness that occurs at times other than in the morning?
