Rheumatoid vs osteo vs psoriatic: How to differentiate the pain?

How do u tell the difference between the two pain wise and symptom ?? I know I have both ( diagnosed )

Have you actually been diagnosed with rheumatoid arthritis, or are you just assuming so? Both of our parents suffered from osteoarthritis, and it was passed down to myself, as well as my 3 sisters. I've been dealing with it for almost 50 years in my left knee, along with having it in my other knee, both hips, my lower spine, my right elbow, and in my neck.
My older sister needed hip replacement surgery before her 50th b'day, and also suffered with rheumatoid arthritis in her hands and knees. She was eventually prescribed an injectable medication that she used for more than 10 years, even though it came at the cost of suppressing her immune system, because it's an autoimmune disease.
In August of 2020 she spent a month in 2 different hospitals with severe back pain that turned out to be a massive infection around her spine that was inoperable. Then she suffered a massive stroke during an MRI that left her brain dead. Her husband had to pull the plug a couple of days later so she wouldn't die on her daughter's b'dad. She was barely 64 years old.
Now my 2 sisters and I are left having to deal with osteoarthritis as we get older. My soon to be 60 year old sister had hip replacement surgery almost 3 years ago, and my youngest sister has to deal with it in her hips and knees. I'm 67 years old, and have had several surgeries on my knees, hands, elbow, and my neck. This is all on top of having idiopathic poly neuropathy in my feet for over 10 years.
Don't just assume that you may have rheumatoid arthritis, you need to get a diagnosis from a doctor because it was the underlying cause of our sister's death at way too early of an age.

@tisme rheumatoid is autoimmune and osteo is wear and tear as far as I know.

Yes, @tisme, get diagnosed if you haven't already. I have both, and they do cause different problems.

Get a blood test with an RA panel.

how do u know which pain is which??

@tisme you can't know without blood tests. Blood tests will confirm RA. Xrays confirm OA. However there are other types of arthritis like GOUT (a uric acid or urine blood test), which can be debilitating. They can all mimic each other.
Try Tylenol for pain. Try Tart Cherry Capsules (Zazzee brand) for gout.
OA normally just causes joint stiffness. The kind of pain which feels like an inflammatory reaction is either Gout or RA. If you have RA you need medicine which only the doctor provides. See an arthritis speccialist after you've tried gout remedies to see if that can resolve things for you.

I was diagnosed by a rheumatologist; she has me on hydroxychloroquine ( Plaquenil)

@loriesco
I have osteoarthritis and I have stiffness, inflammation and pain. I don't have RA. Osteoarthritis can be primary or secondary but there is definitely pain involved.

@kjoed53 go get your uric acid level tested. If it’s high, even if it’s in the boundaries, you probably have gout my whole body slows down and gets stiff after over exertion or a change in the weather, the tart cherry capsules and the tart cherry juice, relieve the pain and inflammation that pointed in the direction of the gout. Plus, the fact that my dad had gout.
