Persistent neck pain. For spondalytis.

I am suffering from persostent neck pain and its not going away inspite of using ice pack ,hot water bag, exercises. I have had a back injury about 2 years back which resulted in slight wedging in lower back . this caused me a lot of discomfort and pain. I had to use belts and have attended physiotherapy for months. It got healed but because my job is a sitting job back pain started developing. I had my posture maintained, have been using lower back support. But the back pain always persisted although reduced so much that i dont really care. Now the problem has become complicated about 2 months back. I started developing neck pain. I have tried stretching exercises, yoga and had been using water bags. But all to no avail and the pain keeps going on. Also got tested for spondalytis. Thankfully i havent got it . I also need to visit a doctor. Please suggest should i visit a physiotherapist or a chiropractor or a neurologist?. In the mean time please suggest anything to get some relief.
