Hello. Thanks for asking from HCM. I can understand your concern. Whiplash injury usually recovers on its own in few months. some symptoms mostly sensory may persist for longer duration but healing always occurs. Regarding worrying about injury, first you should rule out any spine fracture or visible spinal cord or nerve injury. It can only be ruled out by X ray of spine and MRI spine. You need to consult doctor for it and get investigated. After your clinical examination and normal X-ray, MRI spine report, you need not to worry. For your symptoms of tingling in extremities and headache, you can follow few tips : Take rest : You can take painkiller like Diclofenac sodium after proper prescription : For nausea, you can take Domperidone or combination of Domperidone-Pantoprazole after prescription : For tingling, you can take Pregabaline or Nortryptiline after proper prescription. : Neck spasm can be relieved by massaging, apply painkiller gel like Diclofenac gel and warm compresses : If still no relief, you should consult doctor. Hope it will help you. Thanks. Take care
