Limp, or weakness, refers to a lack of strength or firmness in a body part, often resulting in difficulty moving or supporting weight. This condition can affect muscles, joints, or bones, leading to instability or an inability to perform normal activities. Limping can be caused by various factors, including injury, illness, or fatigue. In medical terms, a limp may indicate underlying issues such as arthritis, muscle strain, or nerve damage. It can also be a symptom of more serious conditions, requiring evaluation by a healthcare professional. Treatment often involves rest, physical therapy, or medication to address the root cause.
