1. What Disease Causes Pain from the Buttocks Down to the Calf?
Pain radiating from the buttocks to the calf is a common issue that causes discomfort and difficulties in performing daily activities of living. The causes of this condition may be related to several diseases, including:
1.1. Sciatica
The buttock area consists mainly of muscle and fat tissue, so it is rarely injured by impact or accidents. Therefore, most cases of pain radiating from the buttocks down to the calf are caused by conditions involving the sciatic nerve — the largest and longest nerve in the body, originating from the lumbar spine and extending down to the lower limbs and other organs such as the bladder and intestines.
The cause of sciatica may include sitting in the wrong posture, lifting heavy objects, or prolonged strenuous activity, all of which can compress the sciatic nerve and cause pain accompanied by tingling sensations radiating from the buttocks down to the calf.
In addition, any musculoskeletal or neurological condition that compresses the sciatic nerve can result in pain radiating along this pathway.
1.2. Piriformis Syndrome
Because the sciatic nerve passes beneath the piriformis muscle, inflammation, hypertrophy, or spasms of this muscle can irritate the sciatic nerve, producing symptoms similar to sciatica — including spasms and sharp pain in the buttocks radiating down to the calf.
Piriformis syndrome is often seen in office workers, drivers, or individuals whose occupations require prolonged sitting. It can also result from trauma caused by accidents.
1.3. Herniated Disc
In many cases, pain from the buttocks down to the calf is due to a herniated disc. Disc degeneration is part of the natural aging process but can also occur after spinal injury.
Intervertebral discs act as cushions between vertebrae, absorbing shock. When discs degenerate or herniate, they can compress nearby nerves, causing pain. Herniation most often occurs in the lumbar spine, resulting in pain radiating from the lower back to the buttocks and legs.
1.4. Sacroiliitis
Sacroiliitis is inflammation of one or both sacroiliac joints, which connect the lower spine to the pelvis. Pain from sacroiliitis may affect the lower back and buttocks, radiating down to the calves. The pain worsens when standing for long periods, climbing stairs, or taking large strides.
1.5. Lumbar Spondylosis
Lumbar spondylosis is a common cause of lower back pain, especially in older adults.
As degeneration progresses, bone spurs may form and compress the nerve roots, causing pain radiating from the lower back to the buttocks and down the legs.
1.6. Bursitis
Bursae are small sacs that produce synovial fluid to reduce friction in joints. Overuse can irritate and inflame the bursae.
Hip bursitis may cause pain radiating from the buttocks to the calves, accompanied by redness and swelling over the affected area.
These are some of the conditions that may cause pain from the buttocks down to the calf. Early recognition and timely management are essential to prevent complications.
2. Is Pain from the Buttocks Down to the Calf Dangerous?
Pain radiating from the buttocks down to the leg is most common in middle-aged and older adults, but it is increasingly seen in younger individuals starting from age 30. This can be a warning sign of serious underlying diseases if not promptly diagnosed and treated.
Because the buttocks mainly consist of fat and muscle, they are rarely affected by trauma or direct injury. In most cases, this pain is related to compression of the sciatic nerve.
However, in some cases, the cause may be tumors or infections, which, if left untreated, can lead to paralysis or permanent disability.
Therefore, when experiencing pain from the buttocks down to the calf, the best approach is to visit a medical facility for proper diagnosis and professional treatment.
3. What Should You Do When You Have Pain from the Buttocks Down to the Calf?
Most cases related to sciatica improve within 4–6 weeks. You can relieve pain using the following methods:
- Apply warm compresses to the painful area to reduce pain and swelling (if present).
- Perform gentle stretching exercises designed to relieve sciatic nerve pain.
- Maintain light physical activity and avoid prolonged sitting or lying down, as immobility can worsen symptoms.
- Consult a doctor or pharmacist about appropriate pain medication. Over-the-counter NSAIDs or paracetamol are usually ineffective in these cases; stronger prescription drugs may be necessary.
- When lying on your side, place a pillow between your knees, or when lying on your back, put a small cushion under your knees to reduce strain and pain.
4. When Should You See a Doctor?
You should see a doctor if your symptoms do not improve after several weeks or if they worsen and interfere with daily activities of living.
Seek immediate medical attention if you experience:
- Sciatic pain affecting both legs.
- Numbness or weakness in both legs that is progressively worsening.
- Numbness around the buttocks or genital area.
- Loss of bladder or bowel control, such as difficulty urinating or incontinence.
These symptoms may indicate serious neurological involvement.
The above information outlines the main causes and management of pain from the buttocks down to the calf. If you experience this condition, it is essential to consult a specialist as soon as possible, as it may be a sign of diseases that, if untreated, can lead to severe complications.
