What is the difference between osteoarthritis and rheumatoid arthritis?

I've been looking into this too! From what I gather, OA is more like the 'mechanics' of your joints wearing down over time, often from age or overuse. RA is an autoimmune issue where your body's immune system mistakenly attacks its own joint lining. It's interesting how different the causes are even if the symptoms can seem similar initially.

Please, if you are having joint pain, don't try to self-diagnose from the internet. Osteoarthritis is usually from aging and joint damage. Rheumatoid arthritis is an autoimmune disease. Both need a proper doctor's diagnosis and treatment plan. Get it checked out by a specialist for sure.

I just dealt with figuring this out for myself! Osteoarthritis, they told me, is basically wear-and-tear arthritis, usually from older age. My mom has it, and her knees hurt. But my case was Rheumatoid Arthritis, which is when your immune system attacks your joints, and it feels different, more inflammatory and symmetric. It was a long journey to get diagnosed, but getting the right treatment for RA has made a world of difference for me.

Okay, so Osteoarthritis is degenerative, it's like your joint cartilage wearing out, often age-related. Rheumatoid Arthritis is an autoimmune disorder where your immune system attacks your joint lining. The diagnostic tests for RA can be quite specific and expensive, involving blood tests for auto-antibodies. So, be prepared for that if you or someone you know needs diagnosis, and ensure your health insurance covers it.
