I soaked the foot in the hottest water I could stand. Within 30 minutes the pain was gone, the hole in the waders patched, and I was back fishing for red drum.Oof
I hear it’s the worst. It is known to be more painful than a bullet ant. Luckily the pain is really the only danger (well infection of the wound and the wound too of course) but the venom can be so painful it causes cardiac arrest in very rare instances. So the key after being stung is to stay calm, hot water, and potential use of pain reducers.
Not an expert though, I just work in toxicology and have basic field medical training.
