I train regularly (5 days a week), back still hurts. It is super possible to have imbalances even with regular training. Muscles that are weak will not be engaged during compound lifts unless specifically made to engage, either through isolation exercises, or through awareness. A personal trainer or physical therapist can help with either path.
