I am a 33-year-old male. My weight is 158 pounds, and my height is 5 feet 7 inches. For the last four weeks, I am suffering from severe neck pain that has spread to the shoulder. So two weeks before, I visited a doctor. He said that muscles got stiff and has prescribed tablets and advised physiotherapy. Even after that, there is no difference. So when I took an X-ray, he said there is a mild gap in the bone and said that I am suffering from cervical spondylosis. The medications that he gave are Ultracet, Renerve, and Pregabalin (Pfizer company) 75 mg. Now the problem is, stiffness has gone, but the nerve pain is uncontrollable while sleeping and walking, and I feel that these tablets are not showing any difference. So now he is asking me to get an MRI of the spine. Even after using such powerful medications, why is there no difference? Is there anything serious about this?
