There are certain times when massage to an area might have to be avoided or massage altogether must be. This is why it is extremely important to share with your therapist all of your medical history and any changes that may happen between sessions. Prior authorization from your medical doctor may be necessary to proceed with massage in a safe manner. Issues that normally are absolutely contraindicated meaning massage is not advised include deep vein thrombosis, blood clots, aneurysms, cellulitis, and phlebitis. If you have a contagious disease or situation, it can be helpful to share this information with your therapist. For instance, if you have a rash, massage might spread it from one area on your body to another. If you have a minor cold or are not feeling well, it is up to you on whether to come in or not. Massage may increase the healing process and in doing so may increase the intensity of what you are feeling while decreasing the duration of the sickness. If you are pregnant and are having major complications or have had them during previous pregnancies, massage may not be advised, and you are encouraged to speak to your doctor about having massage therapy. If you have health conditions you are seeing a specialist for or anything related to your heart or kidneys or cancer, please check with your physician regarding massage. Massage helps to stimulate blood flow and in doing so may cause strain on your organs by increasing the amount of particles needing to be filtered. If you are prohibited from exercise for this reason, massage may not be advised. Areas that are actively swollen and inflamed or where the skin is broken may to be avoided.
