Foot cramps in the elderly may be caused by cold or fatigue, hypokalemia, neuropathy, intracranial lesions, etc. Different treatments, including conservative treatment and surgery, are adopted for different causes. 1. Cold or fatigue: Cold causes increased excitability of local muscles, and excessive fatigue will cause the muscles to accumulate a large amount of lactic acid, which will affect the blood circulation of the muscles and lead to cramps, which should be kept warm, reduce the amount of exertion, and rest, and at the same time, can be relieved by foot massages, footbaths, and physiotherapy. 2. Hypocalcemia: When hypocalcemia occurs in the body, the excitation threshold of the neuromuscular junction is lowered, and the intensity of a slight stimulus can excite the muscles, thus producing contractions leading to foot cramps. Middle-aged and elderly people with hypocalcemia can prevent and relieve foot cramps by taking calcium supplements. 3. Neuropathy: For example, herniated lumbar discs, cervical spondylosis, spinal stenosis, spinal cord tumors, etc., can cause the nerves innervating the muscles of the feet to be compressed, thus causing foot cramps. 4. Intracranial lesions: such as intracranial tumors, Parkinson’s syndrome, cerebral atrophy, cerebral infarction and other diseases that cause problems in the central nervous system, foot cramps may occur. It is recommended that patients should go to the hospital in time to find out the cause of the disease and targeted treatment.
