Sea urchin stings
Treading on a sea urchin is painful but not usually dangerous, as the majority are non-venomous.
The spines are fragile and break off in the skin. Superficial spines can be dissolved by soaking the affected area in vinegar several times per day and/or applying a vinegar compress.
If the area shows signs of infection, antibiotics may be necessary. Rarely surgical removal of a deep spine may be necessary.
