Contraindications happen when an increase in lymph flow would be detrimental. Contraindications can either be absolute or relative. The physician can override relative contraindications if he or she finds good reason, but the absolute contraindication cannot be overridden.

Absolute Contraindications:

• Acute inflammation – caused by bacteria, viruses and poisons are contraindicated. Tissues will be red, hot, and painful with congestion accompanied by fever. Lymphatic drainage will push these substances into the lymph channels before the body has a chance to eliminate them. This way one can spread the toxic substances throughout the body. It is best to wait a few days until the condition is not acute and the body has had a chance to clean up the area.

• Malignant tumours – there is a fear of spreading the cancer.

• Thrombosis – can lead to free floating blood clots in the circulatory system.

• Major heart problems – if the heart is not fully functioning, oedema can be lymphodynamic due to a lack of venous return. Pumping more fluid in the heart it may stress it more than the actual condition.

Relative Indications or Precautions:

• Kidney problems – check with the physician before treating.

• Bronchial asthma – this can stimulate the vagus nerve bringing on an attack.

• Thyroid problems – no treatment around the throat.

• Medications – fear of increasing the dosage by draining the interstitial spaces.

• Chemotherapy – fear of increasing the dosage by draining the interstitial spaces.

• First three months of pregnancy – fear of miscarriage.

• Removed spleen – recommend shorter session first.

• Menstruation – MLD can increase the flow.
