I'm sorry to hear about the sciatica pain you're experiencing. Sciatica pain, which affects the leg, often results from irritation or compression of the sciatic nerve and can occur without an obvious injury.

Here are some steps you can take to manage your symptoms:

• Rest and avoid activities that worsen the pain, but try to keep gentle movement to prevent stiffness.
• Apply heat or cold packs to the painful area to reduce inflammation and ease discomfort.
• Over-the-counter pain relievers like paracetamol or nonsteroidal anti-inflammatory drugs (NSAIDs) may help, but use them as directed.
• Maintain good posture and avoid prolonged sitting or standing in one position.
• Gentle stretching exercises for the lower back and legs can sometimes relieve nerve pressure, but avoid any movements that increase pain.

Since your pain has lasted for several days without improvement, it is important to consult a neurologist or an orthopedic specialist. They can evaluate your condition thoroughly, possibly recommend imaging studies, and discuss treatment options. In some cases, medications like gabapentin combined with vitamin B12 (as in Gabaneuron 100 Tablet) are prescribed to relieve nerve pain, but this should only be taken under medical supervision.

If you experience worsening symptoms such as severe weakness, numbness, or loss of bladder or bowel control, seek emergency medical care immediately.
