Detailed Answer:
Hello,
Thanks for posting your query.
The description you have given above goes with Cervical Spondylosis.
You have features of Disc Prolapse at C4-C5-C6 levels with moderately severe compromise of neural foramen. There is also cervical lordosis.

Usually, the spinal cord and nerve roots are protected within the spinal canal. The spinal canal is guarded by the vertebrae which separated from one another by a cushion like intervertebral discs. With age, degenerative changes occur which leads to disc prolapse and spinal cord/nerve root compression.
While there is no definite medication or treatment for spondylosis, in addition to the pain killers and oral muscle relaxants, you will have to change your lifestyle for excellent results. Vitamin D deficiency can aggravate the condition. Basic balanced nutrition and exercises are must for a trouble free life. Posture modifications can be adopted by speaking to experts which can help to continue your day to day activities

Speak to your surgeon, if your symptoms don't subside, there are other various treatment options like
1.) Wearing a neck brace
2.) Physical Therapy
3.) Traction
4.) Steroid Injections
5.) Surgical Correction.

Follow these lifestyle modifications,

1.) Apply heat or cold packs regularly.

3.) Do regular physical therapy.
4.) Stick to your treatment plan and go for regular follow up.
5.) Avoid high calorie foods and eat healthy nutritious balanced diet which should include fresh fruits and Green leafy vegetables.
