Hi, I know this is now 7 mos. later, but my sister and I have the same symptoms. My sister got a blood test and she has been diagnosed with Rhumatoid arthritis. Because she was told that RA is genetic I am about to get a test as well. I hope both of you are doing well. If you are still experiencing the same symptoms I would suggest you get a test as well. I wish the best to you both!
I found your post searching for symptoms that match yours almost exactly. I realize this post is more than five months old but I am curious if the pain in your knuckle/finger ever continued or if it got better on its own?
The reason I ask is this: I was searching for these symptoms because of my own finger. Myself, I think I did something while opening a box at work (some of our boxes are glued shut instead of taped) and a lot of what you posted was exactly the same way I feel, when my finger will hurt, (ie: brushing hair, opening something that needs to put pressure on my finger, etc)
I'd appreciate your own reply. Thanks and I do hope yours did get better on its own.
