Deep Heat Spray is used to relieve muscle and joint pain caused by muscle strain, sprains, or physical fatigue. It also helps in treating muscle stiffness and rheumatic pain. The spray works by generating localized heat that helps stimulate blood circulation and reduce muscle spasms, which leads to pain relief. Use before or after exercise or physical activity to reduce the risk of injury or speed up recovery. Deep Heat is sprayed directly onto the affected area from a suitable distance, avoiding contact with the eyes or mucous membranes. Use as needed and can be repeated according to the doctor's instructions.
