May 26, Hank, I'm now past the mid-point of my 6th decade of playing and I do get this symptom too. For one thing two things you may want to play with the instrument pointed as far to the left as you can and for another tilted quite a bit with E-string down more. An excruciatingly twisted and modified Bonmusica shoulder rest might help - I had to take my apart, bend it quite a bit, and reassemble it - but I have not had this problem since I started to use it a couple of months ago, Before that it just sat in a drawer for 5 years - didn't seem to fit me or my instruments. Another factor especially if you play on a different or new violin can be the curvature of the neck cross section. The neck cross section should be elliptical; if it is too circular it can push the left thumb a bit too far to the left and add unwanted tension to the hand. Other than having the neck sanded down, this can be helped by tilting the violin more downward to the right with a shoulder rest.
