Which of the following is a contraindication for cryotherapy?

• A. Normal tolerance to cold
• B. No history of cold sensitivity
• C. Adequate limb perfusion
• D. Hypersensitive to cold

Answer: (D)

Cold exposure can be safely used when a person tolerates cold normally and has good blood flow to the treated area. If someone is hypersensitive to cold, their body may react strongly to even brief cold exposure, potentially causing cold-induced urticaria, severe vasoconstriction, tissue ischemia, or other adverse reactions. This makes cryotherapy unsafe for them. The other statements describe conditions that do not raise safety concerns regarding cold exposure (they indicate normal tolerance and adequate perfusion), so they are not contraindications.
