There is a good explanation for this I read long before...\n\nMost of the time we shake our legs due to some tension.\nThis tension will create an unusual disturbances in nervous system which reaches the brain as a wave.. the immidiate responce of the brain to this fluctuations will come ut in form of "shaking"....\n\nI dont remember from where i read this info..buthopefully this info will help you to some extent\ngoodluck!

You will have an uneven heart beat rhythm.  But that is all you can determine by yourself.  You need to have a heart monitor to tell for sure.  Unless this is a diagnosed condition in you then you know if it is happening again or not.\n\nNow when you say you jolt, if that is your legs or arms or what ever...\n\nThen it is most llikely acondition called restless leg syndrome and there is medication to stop that\n\nBut as always  GO TO THE DOCTOR NOT YAHOO\nEven though some Doctors are Yahoo's

As a general rule, it is usually one or the other that appears to fall asleep.  When a person is a diabetic, especially for a long time, they can develope such a thing called diabetic neuropathy.  This is when a limb, usually a leg or foot or both on one side becomes numb.  As a diabetic myself, this happened to me back in 1996.  It is scary sometimes and makes you really pay attention to your eating habits and making you take care of yourself better by regularly checking your blood sugar by using a meter.  Proper exercise and eating right will not correct neuropathy but it may prevent it from happening to other limbs in your body.\n\nAs for the shakes, it is common for that to happen.  That's why it is important for you or anyone with diabetes to eat regurlarly and don't skip on meals.  I hope this was helpful for you, good luck!

I think that skinny people shake more but, with stimulants anyone will shake. Also, if a person is nervous or scared they will shake. It just happens that shaking although uncomfortable does cause weightloss. Therefore, "shaky" people are more likely to be skinny.

Yeah, it's a side effect of the adrenaline and collagen that your body releases during stressful times.  Mother Nature didn't intend for us to be put in the kind of stressful social situations that we find ourselves in sometimes, but our body doesn't know the difference.  \n\nWhen you get stressed out, your body illicits the same response that it would if you were being attacked by a grizzly bear.  Your body uses adrenaline and collagen to prepare your body for the "fight or flight" response.  Basically, it is a way for your body to maximize the use of your muscles in the shortest possible time period.  \n\nWhen you don't use that energy, your body might start to use it automatically, resulting in uncontrolled shaking.

hormone isn't secreted when you shake your head. hormones are a chemically controlled substance that don't come out on a whim. \n\ni have a feeling that neurotransmitters are the culprits. neurotransmitters are sent throughout the body, Endorphins, which make you happy, might be the cause of this. \n\nheightened blood pressure, and lack of oxygen might increase the intensity of the neuotransmitter, which would lead to intense pleasure! the rapid movements of the nerve impulse to the synpases of the nervous system are the real technical cause..\n\nmaybe you're just shaking your head too hard.. and you're feeling light-headed. with all of the blood down there, i wouldn't be surprised that the dizzy feeling is from lack of blood! \n\nenjoy!

It's probably a habit or reflex. Maybe it's a sign of nervousness. I think it's cool when they do it.

It's to keep your balance.  While you are walking, actually your body is completely off the ground for a split moment.  So, you need to keep from falling on your ass.

all of the above are true..\ncould be triggered by neurologic conditions, muscle fatigue, stimulants, hypoglycemia and so on.  \nIf you experience it after using the involved muscle group, probably fatigue.  \n\nParkinson's causes what's called rest tremor.  It trembles while resting but trembling goes away when one starts moving around.  That's just one of the example.\n\nIf you experience it often, you should consult your family physician to rule out anything serious.

It's because when you're still for too long your circulation(blood flow through body) slows way down and doesn't get all through your extremities (arms and legs) properly.  That's what makes you feel kinda tingly. That's your body's way of telling you it's had enough of the computer chair and would like to go to bed.  Or get up and do some aerobics!

Because our bodies wear out!  :D

What they are doing is stretching the tendons when they strike you. Your body should have a natural tendancy to contract the tendon, therefore contracting the attached muscle. This produces the leg jerk you see if they are hitting your knee. If there is no leg jerk, there could be a problem with your nervous pathways, or with another area of your body. This test can be performed on various joints in the body, including the knee, elbow, and wrist.

This could be due to your anxiety! Are you a person, who worries quite a lot! In such case, you might want to control your anxiety first. Loose motions will automatically go away!

You've probably experienced a muscle spasm in your leg or arm where your muscle contracts and relaxes uncontrollably.\n\nThe diaphragm is a muscle that controls breathing. When the diaphragm spasms, the opening between your vocal cords snaps shut to check the inflow of air and makes the hiccup sound.\n\nThe exact cause of the spasms is not known.

Could be restless leg syndrome. I would ask a doctor.

This isnn't really the place to answer this. If you think it's serious get her to the docs or emergency room. \n\nHowever, my daughter does exactly the same thing. We took her to the doctors and basically they said don't worry. My daughter will stop doing it for a while and then sometimes restart. It seems to be maybe stress related but in her case it's been no great shakes. She got it about sge 11 and is now 14 and eventually you just kinda stop seeing her doing it. I'm sure the doctor gave it a name at the time, but I've forgotten it. It doesn't seem to bother her so we're cool with it, although like you it bothered us at the start.
