Over the last few days I have been annoyed by my right thumb! It is clunking or clicking when I bend it, it gets to a certain position and then I can feel the moddle joint space click as it goes past a point as it bends inwards. I’m trying to keep it mobile. But is it because I type with my thumb on my phone, or could it be to do with the bug I’ve had? I have had post viral arthropathy (a swelling of the joints) a few years ago after a virus and I wonder if it’s that. I just hope it settles down and doesn’t affect my painting.
