I've been using Hurricaine 20% Solution for my canker sores, but I'm starting to worry about the side effects. The package insert mentions some really severe symptoms like methemoglobinemia, which can be life-threatening. Has anyone else experienced any of these side effects? I've had a bit of irritation at the application site, but nothing too serious so far. Should I be concerned, or is this normal? I definitely don't want to risk something as serious as methemoglobinemia, but I also need relief from the pain. Has anyone had any issues with allergies or other serious reactions? I want to make sure I'm using this safely.
