Which sensation is commonly experienced after OC exposure?

• A. An intense burning sensation on the skin and mucous membranes.
• B. A cool, numb feeling across the skin.
• C. A tingling sensation in the fingertips only.
• D. Immediate numbness of the facial muscles.

Answer: (A)

OC exposure mainly irritates nerve endings in skin and mucous membranes, producing a sharp, burning sensation. The active ingredient, capsaicin, stimulates pain receptors (TRPV1), leading to that intense burning that people feel on the skin and around the eyes, nose, and throat. This burning is the most characteristic and common experience after OC exposure, often accompanied by tearing, coughing, and redness. The other sensations don’t fit this pattern. A cool, numb feeling isn’t typical of OC spray’s effect, which is why a cool sensation wouldn’t be expected. Tingling limited to the fingertips isn’t the usual widespread irritant response, and immediate numbness of facial muscles isn’t a standard outcome either; irritation and burning are the hallmark signs.
