Certain medical conditions could require the exercise of caution concerning the advisability of receiving a massage. If you are in doubt and/or under medical supervision, check with your doctor before receiving massage therapy. Other contraindications include: Fever, Infection, Broken Bones, Infectious Disease (including those effecting the skin), High Blood Pressure, Tumors, Open Wounds, Muscle Ruptures, Heavy Bruising, Herniation, Burns, Myositis, Ossificans, Thrombosis, and Bleeding Disorders such as Hemophilia.   In some cases, massage is extremely beneficial for some, but not for others. For example, some doctors claim that massage is contraindicated for cancer, while others recommend massage for cancer patients. Be sure to inform your therapist before beginning your massage session of any new or pre-existing injuries, illnesses, and/or health conditions that you have. Again, when in doubt, check with your doctor.
