Baby had a soft bump on the head four months ago, and there's still a bit of it. Need to go.

Patient's question:

Four months ago

Doctor's answer:

Determine the size of the hematoma and the amount of bloodstain before considering whether it is necessary to drain the blood. Then, apply appropriate antibacterial and anti-inflammatory treatments. If the bloodstain is minimal, you can apply Zheng Honghao oil externally to promote blood circulation and resolve blood stasis.
