You can ask your therapist, "Can you please focus the full hour massage on relieving the pain in my shoulder? Today I don't need my legs worked on, maybe next time I book."
By asking the therapist, he or she will understand what your specific goal for the massage will be. The therapist may need to work on the surrounding muscles that are connected to the shoulder. Be patient, take nice long deep breathes during your massage. Let your therapist know if the pressure is ever too much or if you feel like the area has been a little over-worked. Having a good open communication with your therapist will help you to get the best results from your treatment. This way you will walk away feeling more satisfied and rejuvenated!
