Why Does My Leg Hurt When I Sit or Sleep? Hidden Causes of Radiating Pain

If you’ve ever experienced leg or hip discomfort that seems to get worse while sitting or lying in bed, you’re not alone. Pain that shows up during rest is often overlooked but can point to underlying issues involving nerves, joints, or circulation. At Silver Pain Centre in Toronto, we regularly help patients understand and manage these symptoms before they lead to more serious limitations.

Common Causes of Leg Pain While Sitting

Leg pain that worsens with prolonged sitting is frequently tied to poor circulation, nerve compression, or muscle fatigue. One of the most common culprits is sciatic nerve compression, which can cause pain to radiate from the lower back or hip down the leg. People who spend long hours at a desk or in a car may find that their discomfort builds gradually throughout the day. Inflammation of the hip flexors or tight gluteal muscles can also contribute to pain when seated.
Learning how to relieve leg pain from sitting too long starts with changing position regularly. Standing up every 30 to 45 minutes, using a lumbar support cushion, or adjusting your posture can help reduce pressure on the lower spine and hips. Gentle stretches for the hamstrings, calves, and hip flexors can also provide relief.

Why You May Feel Hip Pain from Sleeping on Your Side

Hip pain from sleeping on side positions is another common issue. Side sleeping places continuous pressure on the hip joint, which can irritate the bursa or aggravate underlying arthritis. This type of pain may feel like a deep ache that sets in overnight and is often worse upon waking.
To minimize pressure, try sleeping with a pillow between your knees to align the hips and reduce joint strain. You can also alternate sides or sleep on your back with a pillow under your knees. If the pain persists, it may be worth investigating for conditions like trochanteric bursitis, hip osteoarthritis, or referred pain from the lower back.

Radiating Pain During Rest: Nerve or Circulatory Problem?

Radiating pain that flares up while sitting or sleeping may also be due to nerve irritation. Sciatica and lumbar radiculopathy are common conditions in which compressed spinal nerves send pain signals down the leg. Unlike muscle strain, this type of pain often feels sharp, burning, or numb.
In some cases, reduced blood flow from vascular conditions can also contribute to nighttime discomfort. This is more common in older adults or individuals with diabetes, and should be evaluated by a physician if accompanied by swelling, coldness, or color changes in the leg.
