According to the most recent issue of the Nation's #1 Reefkeeping Magazine, "Marine fish and Reef," there is an excellent article on Lionfish. It states this on stings. "If you are stung by your lionfish, immediately immerse the wound in hot, nonscalding water (from 110 to 113 degrees Fahrenheit for 30-40 minutes or until pain has diminished) or heat it with a hair dryer. The heat will denature the protein that constitutes the venom and prevent it from spreading throughout your body. Although this should provide immediate relief, it is advisable to also see a doctor." It also goes on to state, "The most common symptoms of lionfish stings is intense pain in the affected extremity and swelling-but nausea, vomiting, delirium, chest and abdonminal pian, difficulty breathing, fainting and fever may also occur."
