Sea urchin injuries are caused by contact with sea urchins, and are characterized by puncture wounds inflicted by the animal's brittle, fragile spines.[1]: 431 Injuries usually occur when swimmers, divers, surfers, or fisherpeople accidentally contact a sea urchin with their hands or feet.[2]
Immediate symptoms of sea urchin injuries include pain, bleeding, redness, swelling, and inflammation. Leaving spine fragments in the body may lead to chronic discomfort, tenosynovitis, and arthritis.
