I get full body paresthesia when lying down after around 45 minutes. Mainly during sleep. It wakes me up at around 4 in the morning. It goes almost instantly when I get up. The paresthesia can be removed from a part of the body - say the torso - by rubbing it. It then increases it in other parts of the body. I can progressively isolate it simply to the hands, Rubbing the hands together will remove it altogether for around 5 to 10 seconds but then returns usually back to the hands but sometimes back to other areas of the body. It cannot be removed totally without getting up. It s often accompanied with mild tinnitus which also only occurs when lying flat. Have spoken with 3 GPs a cardiac specialist (referred by a GP) and no one has a clue of the cause. I say paresthesia but there is no pain, no numbness - just a sort of high speed vibration and warmth inside the limbs.
Hello! Thank you for asking on Chat Doctor! Your symptoms seem to be caused by anxiety or a neurological disorder. I recommend you to consult with a neurologist for a careful physical examination. A nerve conduction study may be necessary to exclude a possible neuropathy with liability to pressure palsies. Although this disorder would cause pain and numbness (which you don't refer to experience). Thyroid hormone levels may be necessary to exclude a possible thyroid dysfunction, which can cause similar symptoms. Hope to have been helpful! Greetings!
