I'm a 28 year old female and I have been having swelling, stiffness and pain of my right index finger knuckle for over 2 years. It started off as a little right itchy bump on my knuckle (it kind of looked like a welt) and it felt like it was on fire. I noticed it would flare up when it would rain and there was high humidity. From there it has progressed to swelling and it is usually stiff. It has been swollen for so long now that it has started to deform my joint. Now my knuckle in my hand of the index finger is starting to swell and it's painful. Both knuckles are continuously swollen. In the morning my finger is stiff and hurts. Sometimes I can barely move my finger. Usually I'll massage the joint and it will start to loosen up. Sometimes my joint feels hot to the touch, but that's only when it flares up. I have been tested for arthritis and it has come back negative, I've also been tested for Lupus as it runs in my family and that has been negative as well. Any help would be greatly appreciated. Thanks.
