Causes and Treatment for Petechiae Skin Purpura

A sudden development of a rash that spreads quickly over hours is a serious indication of an underlying complicated disorder.

Petechiae rashes are the result of some bleeding on the surface of the skin, typical found on the lower limbs but also spread to other areas of the body. Because blood from the affected blood vessel seeps into the skin, it gives the rash its reddish tinge. Whilst age is not a barrier for the infection, it is more commonly seen in children.
