A stingray is a sea animal with a whip-like tail. The tail has sharp spines that contain venom. This article describes the effects of a stingray sting. Stingrays are the most common group of fish that sting humans. Twenty-two species of stingrays are found in US coastal waters, 14 in the Atlantic and 8 in the Pacific.

They will tell you if you should take the person to the hospital. They will also tell you how to do any first aid that can be given before you get to the hospital.
This is a free and confidential service. All local poison control centers in the United States use this national number. You should call if you have any questions about poisoning or poison prevention. It does NOT need to be an emergency. You can call for any reason, 24 hours a day, 7 days a week.
What to Expect at the Emergency Room
The health care provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure. The wound will be soaked in a cleaning solution and any remaining debris will be removed. Symptoms will be treated. Some or all of these procedures may be performed:
- Blood and urine tests
- Breathing support, including oxygen, tube through the mouth into the throat, and breathing machine (ventilator)
- ECG (electrocardiogram, or heart tracing)
- Intravenous fluids (IV, through a vein)
- Medicine called an antiserum to reverse the effect of the venom
- Medicine to treat symptoms
The outcome often depends on how much venom entered the body, the location of the sting, and how soon the person receives treatment. Numbness or tingling may last for several weeks after the sting. Deep stinger penetration may require surgery for removal. Skin breakdown from the venom is sometimes severe enough to require surgery.
A puncture in the person's chest or abdomen may lead to death.
