Thank you for being online.
The numbing feeling you are having in both legs can have all kinds of different causes, as it is a symptom of many different diseases.
It usually arises from damage or disease of nerves.Its most common causes are:nerve compression syndromes, pressure on the spinal nerves such as that due to a herniated disk,high blood pressure, diabetes, stroke,transient ischemic attack.
Also there is possibility of degenerative changes due to age.Joint degeneration is a natural part of aging and over time all people will exhibit changes in their joints consistent with a greater or lesser degree of degeneration.
You need x-rays of spine.Tests like electromyography and nerve conduction studies,certain blood tests,electro physiological studies are required to make the exact diagnosis.
Take tab. Ibuprofen 400mg from the counter. It is available at your pharmacy as OTC(over the counter) without prescription & will help you greatly in pain relief.
So my best advise for you is to please make an appointment with your doctor to have the tests & examination done so as to know the exact underlying cause & then treatment will be done accordingly.
Hope this helped
