Nocturnal leg pain is severe, and this condition is mainly due to the manifestation of mild muscle strain or strain during the daytime, forming local sterile inflammatory lesions that lead to stimulation of the peripheral nerves, which can lead to pain in the leg. At night, when there is less activity and a tendency to get cold, it leads to further accumulation of inflammatory metabolites, resulting in severe pain in the legs. In this case, the muscles of the leg should be kept relaxed and warm, and a warm water bag can be applied to increase blood circulation and promote the metabolism of inflammation. When lying down, place soft pillows under the bilateral knee joints to keep the leg muscles relaxed and avoid pulling and tension. In the lateral position, soft pillows should be placed under the bilateral knee joints and calves to keep the bilateral lower limbs in parallel, so that the leg muscles can also be in a relaxed state. In this case, warmth, heat and muscle relaxation are the key to treatment.
