Ear Pain in Thailand: what to buy at the pharmacy
Painful ear after swimming or diving, or an ear that feels blocked.
Blocked ear or dizzy after diving? That can be a pressure injury or decompression sickness, not wax. Stop diving and see a doctor today.
What to ask for first

Ofloxacin 0.3% ear drops
Antibiotic drops for swimmer's ear: pain when you pull the ear, itching or discharge. Warm the bottle in your hand first.
Keep water out of the ear until it heals: no swimming, and cotton with petroleum jelly in the ear when you shower.
