The clavicle fracture of a 4-year-old child is too tight. Does arm purple affect blood vessels? Do you want to take it to the doctor for examination?

In this case, if the bandage on the shoulder is not fixed and the arm turns purple, it should be congestion caused by tight vein compression. Cannot be oppressed for a long time.

Suggestion:

It is suggested to adjust the tightness of the bandage. Remove venous compression as soon as possible to avoid arm circulation disorder.
