Leg cramps are sudden contractions of leg muscles, often caused by overuse, dehydration, or poor circulation. Massage guns can help relieve symptoms by increasing blood flow and relaxing muscle tissue. Studies have shown massage guns to be effective in reducing muscle soreness and alleviating chronic pain. Popular models include the Theragun G2Pro, Hyperice Hypervolt, and Compex Pro Plus. Users have reported significant improvements in pain reduction and quality of life when using massage guns on chronic conditions.
