Untreated traffic accident sequelae lead to: ① chronic neck/back pain (60–70% develop within 1 year), ② postural problems (whiplash leads to forward head posture), ③ disc problems (small acute injuries become chronic disc disease), ④ psychological issues (PTSD, anxiety while driving), ⑤ insomnia and depression, ⑥ early arthritis in injured joints. Chronic sequelae are much harder to treat than acute injuries. Investing in early treatment prevents long-term problems. Auto insurance covers prevention — use it.
