The rash and skin irritation that occurs with minor jellyfish or
Portuguese man-of-war stings will usually go away with home treatment.
Seabather's eruption is a rash that develops from the
stings of jellyfish or sea anemone larvae. Although these rashes are annoying, they are not

Jellyfish or Portuguese man-of-war stings may cause blisters or
small, shallow sores (ulcers). The skin at the site of the
stings may look dusky or bluish purple. Healing may take many weeks. Permanent
scars may occur at the site of a sting.
Sores usually heal without medical treatment. Wounds should be
cleaned 3 times each day and covered with a thin layer of antiseptic ointment.

heal and prevent infection.
