What are the Purple spots on my forearm?

Purple spots on your forearm could be caused by various factors, including bruising, petechiae (tiny blood vessels that burst), or dermatological conditions like purpura. They may also be a sign of an underlying medical issue, such as a bleeding disorder or an allergic reaction. If the spots are persistent, increasing in number, or accompanied by other symptoms, it's essential to consult a healthcare professional for an accurate diagnosis and appropriate treatment.
