With the finger.... no idea if it will go away. I have had something similar on my wrist, perhaps of all the dancing and teaching and the strain/weight on the joint. It lasted for years. Today it is gone, but I barley do things like handstand or the like anymore.
The finger joint hurts sometimes, but not every time, which makes it hard to not knit 😂 (I did it yesterday...)
I find Sonyas approach very inspiring. And 50 garments a week is also very impressive!!! I think I envy you your sewing experience
