Talk to Neuro Physician on Neck Pain And Stiffness

Assalamualaikum! I want to ask about mother. She is suffering from extreme severe neck pain and muscle spasm since last 4 months. The doctors have diagnosed cervical facet arthropathy. They say there is only supportive treatment for it But it is very frustrating to see her everyday in agonizing pain which gets better by taking analgesics but again gets severe. Physiotherapy also seems of no use. plz help me.
