It is possible for the treatment to hurt, but it eventually becomes a time of pain you’ll find satisfying. Once IMS provides your body with relief and improvements, it makes you want to look past the uncomfortable aspects of the treatment. However, the treatment may hurt during and after treatment, depending on how sensitive the area being treated is. After the treatment, the pain usually lasts for about 24 hours, and is similar to getting a vaccination. Light physical activity can help alleviate the pain faster.
