10 Possible Reasons For Leg Pain And Numbness
Sciatica

Back conditions, such as sciatica, often lead to leg pain as well. Sciatica is an inflammation of the sciatic nerve, which begins in your lower back and travels down to your legs and feet. While sciatica can be difficult to diagnose and its symptoms sometimes diminish on their own, it is often the result of spinal stenosis. Sciatica and other spinal conditions may develop gradually, or they may come on suddenly. Much of the time, what once was tolerable turns into an acute issue. Arthritis or injury can lead to an acute development of sciatica as well.
Fibromyalgia

Fibromyalgia is a highly debated disorder responsible for exhaustion, sleeplessness, mood issues, memory problems, and widespread muscle pain. While the exact cause of fibromyalgia remains unknown, it is believed to stem from amplified pain signals in the brain. Twenty to thirty-five percent of those diagnosed with the disorder may experience tingling sensations and numbness in the lower extremities. These and other symptoms tend to occur after physical or psychological trauma, infections, surgery, or similar events. Fibromyalgia is more common in women than men. Although fibromyalgia involves many symptoms, leg numbness and tingling remains the most consistently pervasive.
