These are absolute contraindications for the use of Cryotherapy treatment; if you have or suffer from any of the following, you will not be cleared for Cryotherapy treatment until your GP has provided a letter of consent: 

• Untreated high blood pressure • Heart attack (within the previous 6 months) or conditions related to heart surgery • Congestive heart failure • COPD • Chronic liver disease • Unstable Angina Pectoris (chest pain) • Pacemaker • Valvular or Ischemic Heart Disease • Peripheral Arterial Occlusive Disease • Deep Vein Thrombosis (DVT) or known circulatory dysfunction • Deep Vein Thrombosis (DVT) or known circulatory dysfunction • Acute febrile illness (such as flu) • Acute kidney and urinary tract diseases Severe Anemia • Cold Allergenic Phenomenon (known allergy to cold contacts) • Uncontrolled seizure disorders • Bacterial and viral infections of the skin • Wound healing disorders (open sores or discharging wound/skin conditions) • Alcohol or drug-related inebriation • Advanced Raynaud's Disease • Polyneuropathies • Pregnancy • Vasculitis • Hyperhidrosis (heavy perspiration) • Uncontrolled Diabetes • A history of syncope/fainting/passing out • Advanced Diabetes • Claustrophobia • Age less than 18 years (parental consent to treatment required)

Fluctuations in blood pressure (due to peripheral vasoconstriction) may cause your blood pressure to increase briefly by up to 10 points systolically during treatment. This effect should reverse after the end of the procedure, as peripheral circulation returns to normal, allergic reaction to extreme cold (rare), claustrophobia, anxiety, activation of some viral conditions (cold sores) etc. due to stimulation of the immune system, temporary redness of the skin, chilblain/skin burns/scarring (very rare).
