Hi, Thanks for your query. from description it seems to be cervical vertigo.Vertigo (dizziness) with this type of origin usually happen when the head is turned or tilted causing compression of the blood vessels that supply the part of the brain involved in balance. I advice you to wear a soft neck collar during the day to help limit neck motion and reduce nerve irritation. You can take nonsteroidal anti-inflammatory drugs such as ibuprofen, Etoricoxib or Diclofen etc. for pain relief and muscle relaxants, particularly if neck muscle spasms occur after discussing with your doctor. Do exercises under guidance of a physical therapist to strengthen neck muscles and stretch the neck and shoulders. I do hope that you have found something helpful and I will be glad to answer any further query. Take care
