Foot Paresthesia Causes

Paresthesia CausesParesthesia is a medical term describing burning and tingling sensation in different parts of the body according to Wikipedia. Paresthesia could be experienced from time to time due to pressure to the nerves caused by sitting for too long, or compressing body parts while sleeping. Stretching and moving around usually resolves paresthesia causes in this case. However, if burning, prickling and tingling is experienced on a regular basis without seemingly any reasons at all, it’s time to figure the underlying paresthesia causes. There are several possible foot paresthesia causes as WebMD explains ranging from nerve damage, viral diseases, trauma and major health conditions.

One of the more common paresthesia causes is peripheral neuropathy triggered by diabetes. High blood sugar levels negatively affect body in many ways, including blood vessels and nerves that become damaged over time leading to loss of sensation, poor blood circulation, numbing of feet and legs. Up to 30% of all foot paresthesia causes are due to diabetes. People with diabetes should examine or have their caregiver examine their feet daily for wounds and sores that may be difficult to heal on top of that.

Alcohol abuse can also lead to peripheral neuropathy in several ways. Alcohol prevents proper vitamin and mineral metabolism resulting in vitamin deficiencies that overtime cause pain and loss of sensations in the feet. Additionally, alcohol triggers nerve damage leading to weakness in the legs, poor motor function, paralysis and even prognosis for amputation.

Nerve entrapment also accounts for a high percentage of the paresthesia symptoms. Tarsal tunnel syndrome is another of the possible foot paresthesia causes. If the nerve that communicates sensation from the foot is pinched because of deformity, injury, or too much movement, the result is pain, numbness, or tingling in the foot.

Poor blood circulation in the legs and feet is another of the paresthesia causes. Peripheral vascular disease (atherosclerosis) is a condition where the blood vessels grow narrower because of plaque buildup. The result is poor circulation in feet. Smoking, high blood pressure, lack of exercise, and high cholesterol are just some of the other foot paresthesia underlying causes. Besides tingling and numbness, other symptoms can include cramping and pain in the calf muscle, color changes of the skin, cold feet, and sores that do not heal.

Injuries are another group of major causes of foot paresthesia. When nerves become crushed or pinched with herniated discs in the spine, dislocated joints or fractured bones, patients usually experience tingling, pain, itching and numbness in feet and legs.

Multiple scleloris along with Lupus and other autoimmune disorders are also responsible for nerve cells and spinal cord damage triggering symptoms of tingling feet, weakness, muscle spasms and pain.

Patients affected with infections diseases such as Lyme disease, AIDS, Herpes Zoster and many others can experience similar symptoms in the feet and virtually all over the body due to toxic substances produced by viruses and bacteria affecting many organs and systems.

Doctors can use variety of ways to increase blood circulation. Poor blood circulation remedies include controlling cholesterol, managing blood glucose if the patient has diabetes, quitting smoking, and getting regular exercise. However, the doctor may need to take more aggressive measures. Medications like anticoagulants and antiplatelets can help prevent blood clotting. A narrowed artery can be enlarged through the use of angioplasty, or a vein can be taken from some other place in the body and used to create a bypass the blocked or narrow artery.
