I think i'm started to show signs of tendonitis, just starting this weekend, in which i spent most of my hours awake practicing. I have some shooting pains up the underside of my wrist to my forearm when I play/put my hand in some positions. One possible problem is that i have always bent my right wrist a little bit (with an angle no less than about 135 degrees.) I don't get the pain with i play with my wrist completely strait, but i can barely play because my fingers are really above the strings and my palm is pretty much on the bass. Keeping my wrist bent is the only thing i can think of, but i kind of need a bit of leverage about the strings for my right hand, and i still feel the pains in my arm with a strait wrist, they just aren't as present.
