London: There could be a wide variety of different causes. Pain in the legs can be due to a skin problem, such as dryness and eczema, which is common in older people, or to sluggish circulation. Arthritis in either the knee or hip joints, or even in the spine (which can put pressure on the nerves supplying the legs) could also be to blame.
Alternatively, the burning could be a side effect of medication, such as drugs used to treat a heart condition or high blood pressure. So she really needs to see her GP to get this sorted out. Sometimes a burning sensation is accompanied by jerky movements in the legs, especially at night.
Arthritis Treatment and What Causes Burning Sensation
Known as ‘Restless Leg Syndrome’ this can be linked to iron deficiency and also diabetes, though in most sufferers there is no identifiable underlying cause. However, treatment with drugs that raise dopamine levels in the brain, such as levodopa can be helpful. These are available on prescription from her GP.
This problem is not unusual, although it is often also associated with lightning or stabbing pains in one toe, usually the second or third (counting the big toe as the first). The area where you feel the burning sensation is in the ball of the foot — medically referred to as the forefoot — under the top or heads of the metatarsal bones, the five long bones in the feet that connect to the toe bones.
This pain is known as metatarsalgia, and it most commonly occurs between the top of the second and third metatarsals. Typically, it feels like you’re stepping on a stone and walking barefoot often makes the pain worse. It is relieved by taking the weight off your feet by sitting or lying down.
When the pain feels like burning, or there is numbness in one or two toes, this suggests the problem is a neuroma that’s formed on one of the nerves supplying the toes.
Morton’s neuroma, to give it its technical name, is where the nerve becomes squeezed in the gap between the bones, causing swelling or thickening of the nerve. It’s probably the result of a lifetime of repeated pressure (wearing tight shoes, for instance). via dailymail
