 For example, your timber rattlesnake. Another reason why I recommend going in by 911 is they can cause airway and face swelling. It's not an allergic reaction. They don't always do it. Not every year do we get all that many. And that is life-threatening because you can lose your airway. And so you need to go in very quickly. Again, if you're not having difficulty breathing, shortness of breath, chest pain, concerning symptoms, call a poison center. Get an expert doctor.
