![]() If a neuropathy leads to impairment of joint position in the legs, the person becomes more dependent on vision for balance. We are unconscious of this type of sensation from our limbs. This type of sensory information normally allows us to do such things as touch the tip of the nose with a fingertip with closed eyes. In these cases, sensory fibers that carry information about joint position to the brain have degenerated. In moderate-to-severe polyneuropathies, balance may be affected. Only when the physician applies light touches or a vibrating tuning fork or the sharp end of a pin to the skin does it become clear to everyone that sensation is impaired.Īn unfortunate paradox of peripheral neuropathy is that the numbest areas of the body also tend to be the most painful. Patients may be unaware of these problems because pain in the affected body region overrides any appreciation of the numbness. Impaired sensation is a feature of almost all peripheral neuropathies. Even very light sensations, like bedsheets being drawn across the feet, may cause severe discomfort. ![]() Also, the feet may feel swollen or bound up. For example, when a patient with polyneuropathy steps on a small pebble, it may feel like a sharp piece of glass is cutting into the sole of their foot. Commonly, this manifests as increased sensitivity to pressure. Tactile sensations are often altered in body regions affected by peripheral neuropathy. Electric shock sensations may go up or down the legs and feet. Pain from a peripheral neuropathy is called neuropathic pain. ![]() A pins-and-needles sensation may also occur in the feet. It may also feel as though something is stuck between the toes. Patients with polyneuropathies often describe the sensation that a thin layer or film is surrounding their toes or the soles of their feet. Odd spontaneous sensations are often the initial symptom of a peripheral neuropathy. Tingling and Other Spontaneous Sensations The initial symptoms generally depend on the nature of the underlying damage to the nerve. Peripheral neuropathies present as pain, numbness, tingling, and, sometimes, weakness.
