There are many causes of leg pain which can occur suddenly or slowly. Leg pain can also occur immediately after an injury or the onset of symptoms can be delayed.
Symptoms can include a sharp or dull pain. There might be burning, aching, tingling, numbness, pins and needles, or weakness. Leg pain commonly occurs with pain higher up in the buttock, lower back or spine, and down into the foot.
Severity can be anywhere from 1 to 10, or from mild to severe.
Sometimes people can be very unwell if there is a more serious cause like an infection or fracture. If it is associated with peripheral neuropathy or vascular disease there may be changes in colour of the leg, feet with or without ulcers and slow healing wounds.
If there is an infection, the area could also be red, swollen and warm.
