Fire coral sting
When a victim brushes against the projecting tentacles, the nematocysts fire and inject venom causing immediate burning or stinging pain. Rubbing the area will worsen the envenomation and subsequent pain. The area of contact may develop pinpoint red lesions. Edema, blistering, and urticaria are common. The blisters may develop into pustules. Resolution of lesions may take 3-7 days without treatment. Hyperpigmentation of the affected area may last 4-8 weeks.
Nausea and vomiting have been reported but are not common.
