What Does This MRI Test Result For Left-sided Neck Pain Indicate?

I have been having pain in my left side of the neck since April. My MRI Reports says, There is a disc dehydration with an associated small broad-based disc osteophyte complex shown at C4/C5 level which contacts the cervical spinal cord without causing any significant cord compression. There is no evidence of any exit foramina narrowing or any other neural compression shown . My doctor has referred to Physical Therapist. with pain killers and exercise the pain is in control. My question is that I am on constant pain killers every 4 hours for the last 12 weeks. For how long I have to continue eating the pain killers as missing or delaying one dose cause the pain return. Is there any chance it can get better or at least doesn t get worse.
