My son also have this before. Last time, he was getting hight fever. We actually measure him every hour hours and the rate is approximate 101 degree. So, I already take him to bath to cool down. However, within 10 miniutes time, his is very very sick and finally, he 抽根. I never expect this happen and so frighten. This last for about 2-3 miniutes. Then, he stop. At that time, he told us he is freezing and because of lack of experience, we bring him a lot of cloth to cover. This is really a big mistake. The reason is when we arrive hospital, he is 106 degree. I can't believe because I never heard this rate. All nurse is so serious and bring him for immediate treatment. Finally, he is cool down. But, doctor still told us if before 6 years old, he had 抽根twice, then he has to take medicine for 2 yaers. So, I doubt why your doctor made this decision when he just tried once. I suggest you check with more doctor because there still side effect of the medicine.
