Marine Stings and Scrapes - Topic Overview

Portuguese man-of-war stings produce immediate burning pain and redness where the tentacles touched the skin. The affected area develops a red line with small white lesions. In severe cases, blisters and welts that look like a string of beads may appear. Stings that involve the eye may cause pain, swelling, excessive tears, blurred vision, or increased sensitivity to light. Severe reactions are most likely to occur in children and small adults. Severe toxic reactions to the venom can also occur.

Stingrays are members of the shark family. They have sharp spines in their tails that can cause cuts or puncture wounds. The spines also have venom. Stingrays do not bite but can suck with their mouths and leave a bruise.

Coral scrapes and cuts are common injuries that may occur when you walk on a beach or swim, snorkel, or dive in warm water. Coral polyps, the soft living material that covers the surface of coral, can be easily torn away from the rigid and abrasive structure underneath if you touch, bump, or fall on coral. A skin infection may develop when small pieces of coral, other debris, and bacteria get inside the wound. Scrapes and cuts from sharp-edged coral may take weeks or even months to heal.

Check your symptoms to decide if and when you should see a doctor.
