Re: Thumb Knuckle Pain and Swelling
It could be something as simple as a bone spur in the joint that came from an injury years and years ago. That is what arthritis does...builds new bone to try to fix a problem but it tends to build it in the wrong area.
Try putting a piece of tape(paper tape or any kind of tape you use to hold on bandages...not duct tape)and put it around the joint. Doesn't have to be tight, just tight enough to remind you not to bend the joint......kind of like a splint for it. And then wear it for a day and see if it helps. If it does, then you know it's something inside the joint or a tendon problem. By splinting the thumb, you may find that it starts to heal by itself or that it doesn't help at all(and that tells them something as well) or that it's in the joint.
Your doc may order x-rays but really, the only doc's who can help with a thumb are those who know the anatomy of the hand inside and out. So if you need further treatment, see a hand orthopedist for further evaluation. They call the hand a "mine field" because of all the nerves and tendons and it really is.
But you can safely tape it up and see if it helps. That is what my rheumatologist has me do and it has helped me for years. Reminds me to not move it and any rest of a hurting joint helps.
Hope this helps.................Jenny
