I'm taking several physics/math courses this term, and I have no choice but to be writing constantly while taking notes and doing problem sets. My handwriting is very messy unless I grip my (mechanical) pencil tightly, and that ends up causing my wrist to start hurting (which has been a slight problem in the past, but never persistent like it is now). It doesn't hurt enough to prevent me from writing, but I'm worried because it's starting to get worse, and I can basically never give it a break because of my classes. Does anyone else ever have this problem? Or do I just press my pencil down way too hard?
