What Causes Pain In Neck Radiating Towards The Spinal Cord?

Hey, I'm a 17 year old male. I work out about 5-6 times a week for about an hour and a half each day. I've been getting this pain in my neck recently, I feel the pain most when I bend my head back towards my spinal cord. It also feels very uncomfortable when I move my neck left to right. Any ideas of what this is?
