welcome to hcm
(AS) is a diagnosis based on clinical features, xray sacroiliac joint
or mri sacroiliac joint.blood test ie HLA B27 is not useful for diagnosis. so even if it is negative does not tell us much.more important is MRI sacroiliac joint. If the result says both side (left and right) sacroilitis your diagnosis is def AS. if not you may be having other types of spondyloarthropathies.
you need a RHEUMATOLOGIST
to help you out, be it in INDIA or elsewhere.
whatever be the diagnosis, physiotherapy
, occupational therapy
form a very important element of management of all types of spondyloarthropathies.
though there are medications to help you out , slow progression, but no permanent cure.
physiotherapy and occupational therapy delay the progression of deformity.
hope this is helpful
