Back Pain on right side. Help. (klywin)

I have been experiencing back pain only on the right side from last 2 years. It is continuous which restricts deep breathing. I can feel the pain when I am sitting, walking and mostly when I'm sleeping. I was diagnosed with tuberculosis at the same from which I recovered within 12 months, but the pain still persists. I have done CT Scan, MRI Spine and CT IVP, but the results are normal. Orthopedic and Urologist conclude that there is no issue. I also visited Physiotherapist and followed the exercises for at least a month, but no improvement. No doctor is able to identify the root cause of this issue. They only say that it is a muscular pain and it is only in your brain, ignore it. I have spent huge amount of money in visiting different doctors and for various tests, hence, I am fearing to believe any other doctor now, maybe they will also charge money and then say that it is muscular pain only. I had raised a similar query few months ago but no help.(Klywin)
