Swimmer's ear in Bali

I always end up with "swimmer's ear", in the surf and in swimming pools.
Prevention: ear plugs (Blu-tak works if you don't have the expensive gel ones)

Treatment:

• 2 drops of vodka in the affected ear, every few hours
• 2 Panadols every 4 hours
• Ear drops, if Vodka doesn't work.  After 24 hours of treatment, all good.  Price 55 000 rupiah (50 000 rupiah on Jalan Legian, near Jalan Melasti)  A bargain.
