Hi all, I have arthritis in my fingers and thumbs (among many other places) and struggle to write more than a couple of sentences at a time. I've just started a course through church which includes a workbook but I'm finding it painful. My thumb is the worst joint and have looked at arthritis pens and wonder if anyone has tried any? I'm thinking of either an easy start roller ball or are the rubber grips you can use on any pen better. Thanks in advance
