desperation drove me to massive Google search on the jerking that happens to me every night when I stop reading and turn off the light to sleep and again in the early am and I can't go back to sleep cos I'm so busy jerking
I get a building sensation than wham! a huge jerk seems like in my tail bone and thighs , it is over so quickly that I can't tell exactly where it is coming from.
I take magnesium, electrolytes in coconut water , I weigh 124 pounds so not fat.
this is going on now for 6 years - sometimes it goes away just enough for me to stop worrying but 3 nights now and never ending jerks for hours on end , also get giant cramps in one leg and have benign fasciculations that come and go.
I'm thinking I should get an MRI of my spine in case I have some weird tumor or something.
