Adrenaline can hide pain for hours or even days. Many accident injuries, especially whiplash and other soft tissue injuries, show up 24 to 72 hours later, once inflammation sets in.
If you have severe pain, a head injury, numbness, confusion, or trouble breathing, go to the emergency room or call 911 right away. Once serious injury has been ruled out, a thorough musculoskeletal evaluation is the next step. It looks at the soft tissue, joints, and nerves that emergency rooms aren’t set up to assess.
