Yes, I got that when I was forty, one joint at a time. As each new joint gets arthritic it is very painful, especially in cold weather. However, it does stop after a few years. It's the joints with the most wear and tear that are the worst affected - I had to stop knitting for years. Four or five? I am left with strange-looking nodules on the joints. I started to wear fingerless gloves at night, and applied ibuprofen gel to affected joints to get me through. During the day I took ibuprofen tablets, moving on to stronger medication as it started to affect other joints in my body. It's a very sharp pain in the fingers, as I said, it has stopped now. I have started to knit and sew again very recently but wouldn't dream of spending more than an hour or so a day on it in case it sets it off again.
Now that we have started up a knitting club and all of us are 50 or over, it has been very interesting to see how many of us are in pain at the end of the two hour session. I am not, but all the beginners are. So now I make them stop every 20 minutes and flex their fingers.
