Tingling in the legs may be indicative of many conditions or be a side effect of some medications, according to Healthline. For instance, numbness and tingling may be caused by sitting with the legs crossed, standing for prolonged periods of time, poor blood supply to the legs or shingles.
Additional causes of numbness and tingling include multiple sclerosis, radiation therapy, an injured nerve, stroke or an underactive thyroid, states Healthline. In some cases, numbness, tingling or burning indicates a very serious medical condition that requires immediate medical assistance. A person who experiences numbness and is unable to move, has slurred speech, loses consciousness or recently suffered an injury should seek urgent care.
It is normal for people to experience numbness or tingling at some point, according to Healthline. Numbness or tingling that continues without an apparent cause and is accompanied by a rash, feelings of dizziness, muscle spasms or urinating excessively is reason to consult a physician. A person who is experiencing numbness or tingling sensations is likely to have a reduced sensitivity to heat or cold in the affected area. Because of this, temperature changes and pain are less likely to be noticed and can result in injuries such as being cut or touching something hot without realizing it. For this reason, it is best to take precautions against such injuries when possible.
