While most bruises are harmless, certain symptoms warrant immediate medical attention. Look for signs such as bruises that appear suddenly and are very large, bruising that is accompanied by bleeding from the gums or nose, or if you experience unexplained weight loss, fatigue, or a fever.
If you notice any of these red-flag symptoms, seek medical care promptly, as they could indicate a more serious condition such as a blood clotting disorder or an underlying systemic issue.

5. Protect Your Skin From Minor Trauma You May Not Notice

The skin on your arms may be more vulnerable to minor trauma than you realize, especially if you have senile purpura. Try to minimize the risk of bumps and scrapes by wearing long sleeves or protective clothing when engaging in activities that might put your arms at risk.
Be mindful of sharp corners, door handles, and other potential sources of injury around your home or workplace. Gentle handling of your skin can help reduce the occurrence of new bruises.
