Hi, Thanks for your query. seems you are suffering from cervical spondylitis, the giddiness & the sensation of loss of balance in your case is termed as CERVICAL VERTIGO. This is generally a benign condition and is usually self limiting. 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. When you have episodes of dizziness (vertigo)- Do not lie flat on your back. Prop yourself up slightly to relieve the spinning sensation. Move slowly to avoid the risk of falling. Take rest. Resting will help prevent attacks of light-headedness. Do not drive a motor vehicle, operate equipment, or climb on a ladder while you are dizzy. Do not use substances that can affect your circulation, including caffeine, tobacco, alcohol. I do hope that you have found something helpful and I will be glad to answer any further query. Take care
