The sting of the scorpion causes discomfort (moderate to severe), which reduces over a period of time. Discomfort is often described as a painful or burning sensation at the site of the sting. Severe reactions of the sting such as difficulty in swallowing, blurred vision, seizures, uncontrolled eye-movements, thick tongue and breathing problems, often considered a medical emergency, are observed. Deaths due to scorpion sting have also been reported   .
Scorpion venom may or may not require extensive laboratory work, depending on the species of scorpion. Here, the laboratory studies that can be done are mentioned below:
In most cases, the treatment is supportive. It is advised to wash the region with soap and water. Patient may be advised to remove the jewelry as the body can swell in response to the sting. Applying cool compress has proved beneficial in most cases. Analgesics can help relieve pain that ensues after the sting. Choice of analgesic is acetaminophen as aspirin and ibuprofen can aggravate complications. Antibiotics are beneficial only in case of secondary infection .
Severe complications of the scorpion sting are the allergic reactions which may be life-threatening. Signs and symptoms resemble the bee sting such as hives, difficulty in breathing, nausea and vomiting  .
Scorpion sting appears as a barb that contains the protein toxin. This toxin is not pure, but is a mixture of several proteins such as neurotoxin and protein inhibitors along with other similar substances.
The type of toxin depends on the species. This difference is believed to evolve to target a specific prey and vary from species to species. Only around 2% of the scorpions are dangerous to humans. In fact, maurotoxin and chlorotoxin are the two toxins used for the research of the diseases including cancer  .
Scorpion bites are common in the tropical and temperate regions of the globe. Most of the sting occurs during evenings of summer, outside the home. Though accurate data is not available, it is estimated that around 1.2 million people are stung by scorpion per year.
Deaths due to scorpion sting generally occurs secondary to the cardiovascular and respiratory failure within 24 hours of the sting. Children and elderly are more like to be killed by the scorpion sting. Though there is no racial predilection, according to the data, females are more susceptible to the scorpion venom because of lower body weight .
After the sting of the scorpion, the venom enters the human body through the blood (intravenous route). Generally, the peak concentration of the venom is reached after 30 minutes of the sting. It is believed that the more rapidly the venom reaches the bloodstream, the higher is its concentration in the blood with rapid onset of symptoms. The scorpion-venom is a water-soluble and heterogeneous mixture (the scorpion venom is composed of different concentrations of neurotoxin, cardiotoxin, hemolytic toxin, hyaluronidases, histamine, serotonin, etc.). The clinical effects of the venom are neuroanatomic, local tissue effect and neuromuscular with the primary targets being voltage-dependent ion channels. Some of the effects are as follows:
Scorpion sting can be prevented by taking some precaution such as wearing clothes after shaking them, or dislodging the shoes with scorpions. While going to the park, it is often advised to cover the entire body to avoid contact with this Arachnida. Use of pesticides in the regions with significant populations of scorpion can also work. It is also required to brush off the scorpion from the skin instead of slapping it as it is more likely to sting. People who are working in scorpion prone areas must use Scorpion glow or UV light to locate this organism.
Scorpions belong to the kingdom Animalia and class Arachnida. Belonging to the same class as spiders, mites and ticks, scorpions have a stinger at the last tail segment. The scorpion transmits the toxin through this stinger.
Though most of them are harmless, around 40 scorpions can deliver venom that can cause lethal damage to the humans, sometimes even causing death. Contact with scorpions is generally accidental. Scorpions are found in arid regions, temperate regions and deserts. Since the scorpions hunt at night, the chances of interaction with it, increases at night .
Scorpion sting is the transfer of the venom or toxin (neurotoxin and protein inhibitors) from the scorpion to the host.
When one is exposed to the environment with scorpion, there is an increased chance of interaction between this Arachnida and humans. The complications that arise due to this interaction can be moderate (nausea, inflammation and vomiting) to life-threatening conditions. These arthropods are nocturnal that often resists stinging, unless threatened.
Most of the sting of the scorpions brings about only minor signs such as intense pain, numbness, slight swelling, and warmth in the region. Muscle twitching, sweating, vomiting, drooling and high blood pressure, restlessness and irregular heart rate are some of the severe symptoms of the condition.
The doctor can ask about the personal history of the patient. This assists in making accurate diagnosis of the condition. If there are severe symptoms, blood and imaging tests may be performed to assess the impact of the venom.
Once bitten by the scorpion, applying ice-pack to the region is considered as the first step. Removing jewelry from the body can prevent complications arising from swelling. Pain-killers can help alleviate pain. Anti-venom for some of the species of deadly scorpion is available.
