I feel I have to get it out because RA is so misunderstood, even on here, and I find it frustrating. I partially blame the name and the fact that people get osteoarthritis and RA confused. Perhaps it's not explained adequately either.
NRAS (and the other reputable sites) state that "RA is a systemic disease, meaning that it doesn’t just affect joints. RA can affect a person’s whole system, including organs such as the lungs, heart and eyes."
Ok, mini rant over!
