Leg pain at night while sleeping should clarify what is causing the leg pain. The most common cause is due to prolonged walking, standing or strenuous exercise during the day, resulting in excessive lactic acid accumulation within the muscles and inflammation of the fascia, which in turn leads to pain. The pain is mainly manifested as soreness and swelling in the calf area, which can be relieved by pressing with the hand, or by elevating the lower limb to promote local blood circulation, and the soreness and swelling will be significantly relieved. In addition, local hot compress treatment can be applied, such as hot water bags or hot towels, and if necessary, oral non-steroidal anti-inflammatory and analgesic drugs, such as Xilabao capsules or Nimesulide dispersible tablets. Also because of lumbar disc herniation, the herniated disc compresses the nerve, resulting in radiating pain or pulling pain in the innervation area. For this condition, medication is usually required to bring relief from the pain.
