If an elderly person has cramps in the fingers, they should go to the hospital to check trace elements to see if there is a deficiency of trace elements such as calcium ions and magnesium ions. If there is a deficiency of these trace elements, timely supplementation is needed. If there is a calcium deficiency, you need to take oral medications such as calcium acetate capsules or calcium carbonate granules, and drink calcium-rich foods such as milk. Ask the elderly about their medical history to see if there are any muscle spasms caused by strain or contusions, sprains and other injuries, and you can do appropriate hot compresses and physical therapy to promote blood circulation and relieve finger muscle spasms. As the elderly are usually weak, they can easily feel the wind and cold and get cold, so if the weather is cool, pay attention to adding more clothes and keep warm.
