Hello, I have studied your case with diligence. You may need to do MRI spine. Ankylosing spondylitis typically involve spine and hips with other large joint also. There is reduced chest function in this disease. Stiffness in spine is increased you have such stiffness in spine? Clinical examination is also required to diagnose it. You can do blood test for HLA-B27 to confirm it. If all tests are normal you may need proper exercises and lifestyle modifications. Till time continue medication and physiotherapy. Hope this answers your query. If you have additional questions or follow-up queries then please do not hesitate in writing to us. I will be happy to answer your queries. Wishing you good health. Take care
