Costochondritis and Tietze’s Syndrome are NOT mysterious inflammations which nobody understands.
There is a sort of mad disconnect between how costochondritis is understood and fixed in manual physiotherapy in New Zealand, and how it is not understood and not fixed in most other places in the world. Of course it’s not a mystery and of course it’s fixable.
Steve August has a history of costochondritis himself:
"I had costo for seven years myself after a climbing fall onto my rib cage - with all the sharp stabbing chest pain, the breathing difficulties and the fear I was having a heart attack that comes with it. I fixed it after coming through physio school in New Zealand, and haven’t had even a twinge in decades. I can do anything physical - it’s completely fixed."
Costochondritis is a scary and confusing (but not life-threatening) condition with pain where your ribs join onto your breastbone. Tietze’s Syndrome is just costochondritis with enough inflammation to cause obvious swelling at the rib joints on your breastbone - it’s not a whole different entity. Slipping ribs are the same sort of thing where the pain and clicking is further out to the sides at the costochondral junctions, where the bony form of the ribs changes to cartilage.
Important - any acute chest pain should always be seen first (and urgently) by a doctor or Accident and Emergency Department in case it’s your heart. Cheeringly, up to half of acute chest pain isn’t the heart or anything else dire.
