Numbness in the foot should never be taken lightly, particularly when it is not associated with sitting or standing in one position for too long. According to MedlinePlus, there are several medical causes for this type of numbness. One cause is diabetic neuropathy. In diabetes, high levels of glucose circulating in the bloodstream can injure the nerves supplying the extremities. Peripheral vascular disease, called PVD or poor circulation to the feet, can also cause numbness. Other causes include wearing tight shoes, multiple sclerosis, spinal nerve damage from a herniated disc or tumor and a vitamin B12 deficiency.
Step 1
Consult with a physician regarding the cause of foot numbness. The physician may order blood and circulation tests.
Step 2
Sit in a comfortable position without crossing the legs. Sit with the feet elevated if the physician recommends it. Fluid may pool in the feet in some medical conditions, and elevating your feet can help alleviate it.
Step 3
Wear comfortable shoes and socks made of natural materials, such as 100 percent cotton.
Step 4
Get advice from a physician about a proper exercise routine. It is possible for high-impact exercise routines, such as running and aerobics, to cause foot numbness due to the repetitive pounding down of the feet on a hard surface. Exercises that are easier on your feet may be a better option for you.
Step 5
Review all prescriptions with a physician to see whether any of your medications are causing foot numbness as a side effect.
Tips and Warnings
- According to the National Diabetes Information Clearinghouse, nerve conduction studies and electromyography, a test which evaluates how muscles respond to nerve stimulation, may be ordered when you visit the doctor to determine the root cause of your foot numbness. Blood tests can determine whether vitamin levels are too high or low, whether there is a thyroid problem or abnormal electrolyte levels. Take all medications as prescribed. This is especially true for diabetics who need to keep blood glucose levels in a safe range. Foot numbness, called diabetic neuropathy in diabetics, is more apt to occur when blood glucose levels are high.
- See a physician immediately if foot numbness occurs more than occasionally and lasts for an extended period of time. Avoid wearing socks made of synthetic materials because they do not allow for much air flow to the feet. Tight shoes can pinch nerves in your feet, also causing numbness. In medical conditions affecting circulation to the feet, such as diabetes and PVD, ulcers may form if the shoes or socks are too tight. Do not walk around barefoot. With foot numbness for any reason, getting a cut or stepping on a tack may not be felt, and if not noticed immediately, can lead to the development of an infection or ulcer.
