Your MRI scan indicates you have compressionof nerve roots and also compression of the end of spinal cord nerves. You need to see an Orthopaedic Spinal Surgeon for further management. Depending on how bad your symptoms are, you may be advised surgery.

Looks like the nerve is significantly compressed and if symptoms r severe and it is the first episode with no neurological weakness then there is still chance of conservative treatment . If it is not working then  epidural nerve root block can be considered for pain management after a proper consultation If that also doesn't work then surgery can be considered
