It's a lack of circulation or:\n\nParesthesia (paraesthesia in British English) is a sensation of tingling, pricking, or numbness of the skin with no apparent physical cause, more generally known as the feeling of pins and needles. Transient paresthesia is usually caused by inadvertent pressure on a superficial nerve, such as sitting in a position for an extended period of time, and disappears gradually as the pressure is relieved. Other kinds of paresthesia, however, can be chronic and painful, and can come from a wide variety of sources.\n\nChronic paresthesia indicates a problem with the functioning of nerve cells, or neurons. This malfunction, which is especially common in older individuals, is often the result of poor circulation in the limbs, or may be caused by atherosclerosis—the build up of plaque on artery walls. Without a proper supply of blood and nutrients, nerve cells can no longer adequately send signals to the brain. Because of this, paresthesia is also a symptom of vitamin deficiency and malnutrition, as well as metabolic disorders like diabetes and hypothyroidism.\n\nIrritation to the nerve can also come from inflammation to the surrounding tissue. Joint conditions such as rheumatoid arthritis and carpal tunnel syndrome are common sources of paresthesia.\n\nAnother cause of paresthesia, however, may be direct damage to the nerves themselves, or neuropathy, which can stem from injury or infection, or which may be indicative of a current neurological disorder. Chronic paresthesia can sometimes be symptomatic of serious conditions, such as a transient ischemic attack, a brain tumor, motor neurone disease, or autoimmune disorders like multiple sclerosis or lupus erythematosus. A diagnostic evaluation by a doctor is necessary to rule these out.\n\nParesthesiae of the mouth, hands and feet are common, transient symptoms of the related conditions of hyperventilation syndrome and panic attacks.\n\nOther known causes of paresthesia:\n\nAlcoholism \nAnticonvulsant drugs such as topiramate, sulthiame, and acetazolamide \nDehydration \nHeavy metals \nMigraines \nRadiation poisoning

Do you get enough sleep? Eat well? USe drugs/alcohol? If you're healthy then see a psychologist and psychiatrist. This may be a symptom of a variety of psych disorders but I can't say which ones unless I know more symptoms. You need to do exercises to help you feel grounded and do some mindfulness exercises as well. A therapist can help with that.

It sounds like you might have a pinched nerve or poor circulation. If it doesn't get better definitly seek medical attention.

The term sometimes used is paresthesia.  Paresthesia is a sensation of tingling, pricking, or numbness of the skin with no apparent physical cause.  This lack of sensation is caused by a temporary impedance of blood flow to the extremity which results in nerve cells being starved of oxygen and glucose. Additionally, the impedance of blood flow is usually due to pressure on the limb which in turn compresses the nerve cells, making transmission of neural impulses more difficult. Transient paresthesia is the familiar sensation of "pins and needles" felt when oxygen and glucose-rich blood return to the nerve cells which in turn fire at an accelerated rate until they establish their regular transmission rate.

Many  people experience what  your going through, but not many people talk about it.\n Back in  olden times they  called your experience a "night Hag" That paralyzing feeling caused  by "Her sitting on your body and  holding you down"  \nIt's a  thing of child hood past... not many people talk about that theory anymore, although it is in  some books!\n\nNow, as far as going to a Dr.  It may be a good Idea to talk to him..he might want to do  some tests, but most likely he will tell you it's normal and to not worry about it..it happens to everyone..I've had it happen many times!! It is not a fun experience..usually it will go away right away.. the longest  one i have had is like  a few minutes actually!!! THAT WAS AWFUL!!! \n\nwhen it happens to me it's helpful to relax and stay calm.. i  usually imagine my self "fighting it off" and that  usually works.   try moving your upper body  before anything else that has always seemed to help me out too.  if anything talk to your Dr. if you feel necessary..then try looking it up and doing a little research  who knows what  you might find!!

I would say if it's been a while since you got up and started moving around, the feeling should be back... I would call your doctor.  It could've been like a pin stroke.

I think you feel strange because you're not feeling well.  You might want to see a doctor.

It is caused by a vasovagal reaction where your heart beat slows down and your blood pressure drops causing less blood flow to the brain. Happens to me with needles and its kind of embarrassing.

See you doctor.  Maybe you've been under stress or have PTSD (post truamatic stress disorder).

Why try to guess what this is when it is really bothering you? Please, don't put your health in the hands of an amateur forum. Respect your mind and body. You must consult your doctor. (I am a physician myself and this is the best advice I can possibly give you.)

My feet are getting heavy, and I've lost feeling in my toes. What is that odd sensation in my stomach - like rocks weighing heavily?? My back is stiff, so I try to move. Man, my feet are heavy. I move my legs and it's as if someone  tied cement blocks to them. A creeping sensation moves up my legs, and I stop trying to move them. \nMy eyes hurt. My head feels stiff, as if my skin is crunchy. I try to call out, but my mouth doesn;t want to move - like I am wearing a clay mask and it has dried. What is happenieng to me? My fingers are stiffening, and I am now numb to the waist. I can't move my legs!!  I try to scream, but my vocal cords are too frozen. My nose is numb.  My breasts are starting to feel heavy as lead, and I can hardly hold up my head. The numbness creeps downward, and my fingers are like bananas as I try to type. IO amn makl[oing so manny typpos .. I cannnottr type wellllll,... I cannnt breeeaathe .. sdhfgsdajklllllllllllllllllllllllllllllllllllllllllllllllllllllllllll

What side of the bed do you wake up on? If its the same side that your leg is numb then the answer to your problem is that you sleep on that side all night,causing it to go numb.\nWhen you sleep on one side all night you restrict the blood flow going to that area, hence pins and needles or a dead feeling. Try going to sleep in another position if not doing some stretches when you wake up. Let me know how you go...
