I think that you suffer from vertebral column arthritis. To confirm the diagnosis you need:1. Vertebral column X-ray.2. Fibrinogen test.3. Complete blood count.4. Urine test. The treatment of this disease contains non-steroidal anti-inflammatory medications. Massage is also recommended. Consult your neurologist. All the best. </s>
