To treat a stingray sting, immediate first aid and proper wound care are crucial. The main steps are:

• Remove the barb if superficially embedded and safe to do so (not recommended if it pierces chest, neck, abdomen, or causes a through-and-through injury).
• Stop any bleeding by applying pressure.
• Clean the wound with seawater or clean water to remove debris.
• Soak the affected area in hot water (ideally 110°F to 115°F or 43°C to 46°C) for 30 to 90 minutes to denature the venom and relieve pain.
• Elevate the injured limb if possible to reduce swelling.
• Apply antibiotic ointment and cover with a sterile dressing.
• Seek emergency medical care promptly for wound inspection, possible removal of any retained spine fragments, antibiotic prescription, tetanus booster, and treatment for severe reactions or deep wounds.

Medical professionals may use X-rays to check for spine remnants and consider surgery if severe tissue damage occurs. Pain management with over-the-counter medication is also recommended. Watch the wound for infection and follow up with healthcare providers.
