I have studied your case.
As per your symptoms neck pain
can be due to diffuse disc bulge compressing your cervical spine
You may need MRI spine and brain to see for severity of nerve compression.
Your problems like pronouncing problem can be due to lesion in brain.Temporal lobe
involvement can lead to such problem.
Some medication like methylcobalamine with muscle relaxant
and analgesic will reduce pain, you can take them consulting your treating doctor.
You may consult physiotherapist for further guidance. He may start TENS ,or ultrasound
which is helpful in your case.
Also check your vit B12 and vit D3 in your blood.
Hope this helps. Wish her a speedy recovery.
