This happened to me last summer when I was in South Africa.One day，I fell while getting off a bus and got a small cut on my ankle.I45 to wash the cut or put a bandage（绷带）on it.
Three days later，I couldn't put on my shoe because my foot became so enlarged.The pain in my ankle was terrible，and it was moving up my leg.I needed to find a doctor immediately.But in the middle of South Africa，a（n）46 to the hospital looked like this：six hours by car，one day by bicycle，or three days by donkey.
This is when I met Siswana and the leeches（水蛭）.Siswana was a traditional doctor from a village 4 kilometers away.She looked at the cut and pushed on it carefully.Then she put her hand on my forehead and nodded her head.Yes，my temperature was47 .She told me I had a fever and the pus（脓）must get out of the ankle before I could travel to the city the next day to get some antibiotics（抗生素）.
She put a wet cloth on my forehead and opened a small metal box.48 this dirty little box were the leeches which looked like green stones.I put my head back，closed my eyes and tried to think of other things.Then I felt something cool on my skin.Siswana put the leeches gently around the cut on my ankle.Suddenly，I felt them bite and then I didn't feel anything.She smiled to help me49 and tried to make me forget about what was happening on my ankle.An hour later，I found my ankle was bandaged and Siswana was smiling.I thanked her for helping me.
A day later，I travelled 120 kilometers to the next city and got a shot（注射）of antibiotics in a hospital.I'm sure I don't like shots50 they are more pleasant than leeches!
