A self-operated, or therapist assisted, apparatus particularly adapted for massaging a user's body parts affected by repetitive strain injuries such as tendinitis and carpal tunnel syndrome, comprises two clamping arms joined at a base end and provided with an opening at the other end. Flexible massaging members are mounted on opposite medial sections of the arms. A body part may be placed between the two arms of the device to be acted upon by the massaging members, whereby the body part is adjustably clamped between the pair of massaging members and massaged by translating and rotating movements of the body part along an axis perpendicular to the mounting axes of the massaging members. Alternatively, one of the arms of the apparatus may be separated from the apparatus and used independently to massage body parts that otherwise would not fit between the arms of the apparatus.
