She was injured when a lorry and a moped were involved in a collision this morning.
At first the woman - believed to be in her late teens - was feared to be trapped.
But a spokesman for the East off England Ambulance Service said she had escaped without serious injuries.
'It looks like the moped ended up going under the lorry but she wasn't trapped,' he said. 'The patient was assessed at the scene, but has not been taken to hospital for further treatment.
'She was discharged at the scene and given advice on what to do if her symptoms worsen.'
The single-track road was closed in both directions but has now re-opened.
