While massage is generally safe, there are certain conditions that may require caution or modification of the massage techniques. It is important to inform the massage therapist of any medical conditions, injuries, or areas of concern before the massage to ensure that the treatment is safe and effective. In some cases, a massage may need to be avoided or modified, such as in individuals with certain medical conditions or during pregnancy. It is important to consult with a healthcare professional before undergoing a massage if there are any concerns.
