Hi, I am a 38yr old female just dx with being HLA-B27 positive. I have been having back pain for over 2 years now. I am also ANA positive with Rosacea rash that started after being on an antibiotic called Zyvox. I developed MRSA after my 10th left knee Sx. Anyway, my X-ray showed degeneration of my right hip, but my SI joints looked ok. I then got a MRI which just showed inflammation in my disk space. My SI joints again looked ok. I m waiting for my rheumatologist to discuss the MRI report with the radiologist since it seemed confusing to her. Is it possible to have Ankylosing Spondylitis without swelling in my SI joints? I also have snapping pain n my ankles and burning pain in my sternoclavicle joints. Thanks.
