Treatment for stings may include application of hot water, which has been shown to ease pain. [3] [6] Multiple theories as to the mechanism of pain relief from hot water have been suggested. A theory that hot water denatures the stingray venom has been questioned because the temperatures required would need to penetrate deeply into the puncture ...
Additionally, excessive bleeding or signs of anaphylaxis, which would have symptoms such as difficulty breathing, dizziness, abdominal pain, rapid or irregular heartbeat, would be considered a ...
Stingrays can have one, two or three blades. Contact with the spinal blade or blades causes local trauma (from the cut itself), pain, swelling, muscle cramps from the venom and, later, may result in infection from bacteria or fungi. [35] The injury is very painful, but rarely life-threatening unless the stinger pierces a vital area. [34]
Potamotrygon leopoldi is part of a species complex of blackish river rays with contrasting pale spots found in the Tapajós, Xingu and Tocantins basins [3]. River stingrays are almost circular in shape, and range in size from Potamotrygon wallacei, which reaches 31 cm (1.0 ft) in disc width, [9] to the chupare stingray (S. schmardae), which grows up to 2 m (6.6 ft) in disc width.

The Schmidt sting pain index arose from the pursuit of a larger hypothesis: that the evolution of sociality in Hymenoptera was dependent on the evolution of venom that was both painful and toxic. [6] Pain is a signal of damage in the body, but molecules that produce pain and those that are toxic, and actively cause damage, are not the same.
A scorpion sting is an injury caused by the stinger of a scorpion resulting in the medical condition known as scorpionism, which may vary in severity. The anatomical part of the scorpion that delivers the sting is called a "telson". In typical cases, scorpion stings usually result in pain, paresthesia, and variable swelling.
The Starr sting pain scale was created by the entomologist Christopher Starr as a scale to compare the overall pain of hymenopteran stings on a four-point scale, an expansion of the "pain index" originally created by Justin Schmidt. [1] [2] 1 is the lowest pain rating; 4 is the highest.
