I'd like to be added to this discussion too. Sounds like I've stumbled onto what is going on with my chest pain that I've been told is arthritis. I looked it up and it describes perfectly The pain that comes and goes. I feel and broke several ribs 5 years ago. Now I get these pains and sometimes it's so acute that it makes me catch my breath. I'm a small framed, light weight, female, 58 yo with Fibromyalgia, osteoporosis, Osteoarthritis, neuropathy and lumbar replacement. A totally messed up neck.
