問題詳情

Tingling hands, feet, or both is an extremely common and bothersome symptom. Suchtingling can sometimes be benign and temporary. For example, it could result from pressure onnerves when your arm is crooked under your head as you fall asleep. Or it could be from pressureon nerves when you cross your legs too long. In either case, the “pins and needles” effect —which is usually painless — is soon relieved by removing the pressure that caused it.26 It also can accompany other symptoms, such as pain, itching, numbness, and musclewasting. In such cases, tingling may be a sign of nerve damage, which can result from causes asvaried as traumatic injuries or repetitive stress injuries, bacterial or viral infections, toxicexposures, and systemic diseases such as diabetes.Such nerve damage is known as peripheral neuropathy because it affects nerves distant fromthe brain and spinal cord, often in the hands and feet. There are more than 100 different types ofperipheral neuropathy. 27 More than 20 million Americans, most of them older adults, areestimated to have peripheral neuropathy.28 In diabetic neuropathy, tingling and other symptoms often first develop in both feetand go up the legs, followed by tingling and other symptoms that affect both hands and go up thearms. About two-thirds of people with diabetes have mild to severe forms of nerve damage. Inmany cases, these symptoms are the first signs of diabetes. In another 30% of peripheralneuropathy cases, the cause is unknown or “idiopathic.” The remaining 40% of cases have avariety of causes.29 As long as the peripheral nerve cells have not been killed, they have the ability toregenerate. Although no treatments are available for inherited types of peripheral neuropathy,many of the acquired types can be improved with treatment. For example, good blood sugarcontrol in diabetes can slow the progression of diabetic neuropathy; vitamin supplementation cancorrect peripheral neuropathy in people with vitamin deficiencies. General lifestylerecommendations include maintaining an optimal weight, avoiding exposure to toxins, followinga doctor-supervised exercise program, eating a balanced diet, and avoiding or limiting alcoholconsumption. 30 In some cases, tingling and other symptoms of peripheral neuropathy maybe reduced with prescriptions originally developed for treating seizures and depression. 
(A) In many cases, however, tingling in the hands, feet, or both can be severe, episodic, orchronic.
(B) Over time, peripheral neuropathy can worsen, resulting in decreased mobility and evendisability.
(C) About a third of the cases of peripheral neuropathy have a history of tingling in the hands,feet, or both. 
(D) Diabetes is one of the most common causes of peripheral neuropathy, accounting forabout 30% of cases. (AB) Successful treatment depends on an accurate diagnosis and treatment of the underlyingcause of the tingling. (AC) Tingling in hands, feet, or both can be cured as neuro-therapeutical technologiesadvance in the twenty-first century. (AD) All these may relieve the tingling and numbness in hands, feet, or both because they willhelp blood circulation in all parts of our bodies. (BC) Recommendations also include quitting smoking, which constricts blood supply toblood vessels supplying nutrients to peripheral nerves.
