Hemophilia and Inherited Bleeding Disorders

Ruptured vein?



I banged my hand in the bony area between my pointing finger and thumb. A blue lump smaller than the size of a dime immediately swelled. It looks like I may have hit one of my veins. Is it possible that I ruptured a vein and should I worry about an internal infection? Path forward?


A small blue lump which occurs right after an injury can be caused by a small amount of bleeding under the skin. Infection usually does not occur if the skin is not broken. However, it is not possible to make a diagnosis without seeing the injury directly. If you have any question about the seriousness of your injury you should contact you medical care provider.
