Ankylosing spondylitis is not simply a back problem. It is a systemic inflammatory condition that targets the spine, sacroiliac joints, and in a significant number of cases, the gut, eyes, and peripheral joints.

Joint pain is one of the most common and least discussed complications of living with HIV. Studies consistently show that up to 60% of HIV-positive individuals will experience some form of musculoskeletal or joint involvement during the course of their illness — a figure that surprises many people, including some clinicians.

Living with SAPHO syndrome means navigating a condition most clinicians have never encountered, one where bone pain, skin flares, and joint inflammation occur together in patterns that do not fit neatly into standard rheumatology or dermatology categories.

Post-infectious arthritis catches most people completely off guard. You fight through what seemed like a routine infection — a bout of food poisoning, a urinary tract infection, a respiratory illness — assume the worst is behind you, and then, days or weeks later, a knee swells without warning, a heel becomes inexplicably painful, or a finger stiffens overnight.

Joint pain and stiffness appearing days or weeks after a vaccine tend to provoke one of two unhelpful responses: either they get dismissed as coincidence, or they generate alarm that outpaces the available evidence.

If you've been told your sacroiliac joint is "just inflamed" or "out of alignment" and left with a stretching sheet and a follow-up appointment in six weeks, you're not imagining that something is missing.
