You note pain in the cervical spine and pain radiating down to the elbows. You note lack of strength (“cannot push power”) which I assume is weakness of the triceps muscles (lack of push-off). Loss of strength in “picking up weight” is typically from the biceps (a different cervical nerve root) but may be from weakness of wrist flexors which is a C7 nerve root function.
The meticulous physical examination which can be well done in any country can shed light on the diagnosis and point the way for appropriate treatment.
The C6-7 notes significant degenerative changes and osteophytes at that level. That could be consistent with a C7 nerve root compression which would cause pain and weakness as you describe (see section under cervical radiculopathy on website). I do not know what resources you have in your country but I would consider an MRI as the next step, then a cervical epidural steroid injection.
