What happens when an arm is discolored and swollen from a fall?

When an arm is discolored and swollen after a fall, it may indicate a soft tissue injury, such as a sprain or strain, or possibly a fracture. Discoloration often results from bruising due to damaged blood vessels, while swelling occurs from inflammation and fluid accumulation. It's essential to assess the injury for severe pain, loss of function, or deformity, as these symptoms may require medical evaluation and imaging to rule out fractures. Applying ice, elevating the arm, and resting the injury can help manage symptoms until a healthcare professional can provide a proper diagnosis.
