For a swollen foot caused by ocean exposure, immediate treatment should prioritize reducing inflammation and preventing infection, with a focus on rinsing the area with clean fresh water, applying cold compresses, and elevating the foot above heart level to reduce swelling, as suggested by general medical principles and supported by studies on managing allergic reactions and skin infections 1, 2. The treatment approach should consider the potential causes of the swelling, including marine creature stings, thermal injuries from hot sand, or exposure to marine bacteria.
- Rinse the affected area thoroughly with clean fresh water to remove any remaining irritants.
- Apply a cold compress for 15-20 minutes several times daily to reduce swelling and inflammation.
- Take over-the-counter anti-inflammatory medications like ibuprofen (Advil, Motrin) at a dose of 400-600mg every 6-8 hours with food, or acetaminophen (Tylenol) 500-1000mg every 6 hours if ibuprofen is contraindicated.
- Elevate the foot above heart level when possible to help reduce swelling.
- Topical hydrocortisone cream (1%) can be applied 2-3 times daily to relieve itching and inflammation, but with caution due to potential allergens in skin products 3.
- If the swelling was caused by a marine creature sting, soaking in hot water (as hot as can be tolerated without burning, typically 110-113°F) for 30-90 minutes may help neutralize venom proteins.
- Seek medical attention if symptoms worsen, if there's severe pain, spreading redness, fever, or if symptoms don't improve within 24-48 hours, as certain marine infections can be severe and require antibiotic therapy 2. It's also important to be aware of the potential for hypersensitivity reactions to antihistamines or other medications that might be used to treat the reaction 4.
