Suggest Remedy For C5-6 Small Protrusion Of Disc

I have a c5-6 small protrusion of my disc for 2 months that I know of (per MRI) - might be up to a year when I lifted something wrong and had initial pain and stiffness... What are the chances that this will go away with physical therapy and what timeframe? I have intermittent pain, numbness in left arm and daily neck pain around c7 area. What exactly does the disc do over time? Does it shrink back in its place or remain out and at risk for herniation of contents? Thank you for your time!
