Have you ever heard of scorpion fish? I was completely (0) UNAWARE (AWARE) they existed until I trod on one in the sea. I can't 1EMPHASIS enough how painful it was! The fish has a spike which gives you an 2INJECT of a 3POISON substance. It's not dangerous, but you begin to feel extremely 4COMFORT, and the pain just gets worse and worse. Luckily, there was a doctor on the beach - she was a 5SURGERY at the local hospital - and she told me what the best 6TREAT was. I had to bath my foot in warm, salty water and then apply an ammonia-based solution. After my holiday, my foot still seemed to be a little infected, so my local GP gave me a 7PRESCRIBE for antibiotics. Unfortunately, it turned out I was 8ALLERGY to them, so I came out in a red rash all over my body. It was over a week before I had made a complete recovery.
