What the community said
If symptoms could be food poisoning, heatstroke, or infection, don't try to self-medicate with multiple options — the causes are too varied. See a doctor for a proper diagnosis.

Treatment for plankton stings involves applying a corticosteroid (hormonal) cream to the affected area and taking oral antihistamines. This is the standard approach for a toxic-allergic reaction.

Plankton in Cam Ranh can cause severe allergic reactions. Immediately after being stung, wipe the skin with a vinegar solution to help neutralize the venom. Without prompt treatment, welts can persist for weeks even after hormonal injections. Pack antihistamines before your trip.
