I have areas of thickening over a few finger joints that correlate with Wegs activity. They aren't super noticeable and actually just resemble mild callouses. They don't cause any problems. I might have even had them before my first Wegs symptoms, as I have a memory of them and thought they were callouses.

Many AI diseases can cause lumps and bumps, including Wegs. If you're not having other symptoms it might be one of those symptoms that isn't a big deal to live with. I don't really know for sure, though.
