What Causes Tingling in the Legs?
Tingling in the legs may come from several sources; simply standing or resting in the same position for long periods of time may cause tingling, as can animal or insect bites, some medicines and injuries to the spinal cord or nerves, states the National Institutes of Health. As with many other physical ailments, tingling sensations may stem from benign conditions or serious conditions, such as spinal injury or tumors. Sometimes, tingling arises as a side effect from primary sources such as medicines, radiation therapy or chemotherapy.
When patients experience tingling along with numbness, doctors first identify the cause. This helps physicians select the most appropriate treatment method. Treatments include performing certain exercises or simply switching or stopping medicines that may trigger the condition, according to the National Institutes of Health. Sometimes, tingling arises from improper levels of certain vitamins or minerals in the body, such as calcium, sodium and vitamin deficiency, in which case, doctors treat the problem through dietary changes.
While leg tingling may arise from primary sources such as diet or injury, it can also stem from medical disorders. Stroke, diabetes, seizures, multiple sclerosis and an underactive thyroid may produce tingling. Patients should look for certain dangerous symptoms arising along with tingling. Paralysis, difficulty walking and speaking, slurred speech or vision problems, confusion and loss of bladder control may indicate serious conditions; patients with these symptoms should call 911.
