Question

There is a sensation of muscle twitching around the waist and abdomen, similar to phone vibration, and there is a slimming effect on the face. This has been ongoing for several months.

Answer

Muscle cramps refer to the state of involuntary and tonic muscle contractions. Elderly individuals often experience cramps in the gastrocnemius or plantar flexor muscles of the lower legs during prolonged exercise. To relieve them, gently pull the cramping muscle in the opposite direction. Avoid using excessive force to prevent muscle strain.
