My leg was swollenswollen/ˈswoʊlən/L1肿胀的；比正常大bigger than usual because of injury or sickness. I used an AI tool to check my symptoms. It said I might have a dangerous blood clotblood clot/blʌd klɒt/L1血块；血管里的凝固血液a thick mass of blood inside the body that can be dangerous. So I went to the emergency room.
The doctors did an ultrasoundultrasound/ˈʌltrəsaʊnd/L2超声波检查a medical test that uses sound waves to create images of the inside of the body and found four blood clots. They gave me medicinemedicine/ˈmɛdɪsɪn/L1药；治疗疾病的物质something you take to make you better when you are sick, and I was scaredscared/skɛrd/L1害怕的；感到恐惧afraid; feeling fear. But I am okay now, and I am glad I listened to the AI.
