What is the reason for the redness and swelling of the baby's throat with white bubbles?

Patient's question:

No

Doctor's answer:

It could be oral ulcers, which may be caused by zinc deficiency. I suggest taking oral zinc gluconate or taking a combination of vitamin B supplements at the same time. Lozenges containing Huasu are effective.
Recommendation: You can also try using (Xigua Shuang Spray).
