Something I Want to Ask You About

Herpangina. My son had a fever yesterday. I gave him Meilin twice; the fever went down, then rose again. We went to the hospital, and the doctor said it was this illness. The blisters in his throat had ruptured. The doctor prescribed some anti-inflammatory medicine and medicine for the blisters, then said it was normal for him to have a fever. But after Yong Qi came back, he kept running a fever—39.6°C, 39.8°C. I got scared and gave him Meilin again, but once the medicine wore off, his temperature went back up. Has anyone had a similar experience? What should I do? Is 40°C really okay? Right now, I can only cool him down physically or give him Meilin, but he can't take too much Meilin.

Oh, and Yong Qi is eight months old.
