This is mostly arthritis but as PMR is also involved (shoulders and upper arms) I don't think I'm off-piste.
I never thought about thumbs until I got really aggressive arthritis in them. For the last week I have been struggling to clean my teeth. whoever would have thought that cleaning teeth could be sooo painful! I had difficult over the holidays peeling potatoes and chopping veg, but this??
Just another little ailment to disturb my peace in 2020! Think it's time to think about an electric toothbrush.😂
