First, due to the degenerative changes of the knee joint, we should avoid excessive fatigue and heavy load during the day, and pay more attention to keeping warm when sleeping to avoid catching cold. In addition, local cupping and hot compress can be performed to relieve local muscle spasm.

The second is caused by calcium deficiency. If the elderly lack calcium, the muscles and tendons around the joints will spasm, leading to stiffness and discomfort. Calcium can be supplemented and calcium tablets can be taken orally to alleviate this situation.
