Why do i have multiple bruises over my body haven't been hit im only 21 yrs and haven't fallin?

Multiple unexplained bruises can be caused by various factors, including medical conditions such as blood clotting disorders, vitamin deficiencies (like vitamin C or K), or certain medications that affect blood clotting. Stress or excessive exercise can also lead to bruising in some individuals. It's important to consult a healthcare professional to determine the underlying cause and ensure proper evaluation and treatment.
