I only feel the pain when I play with my complete hand, (i.e. little finger and the rest), I don't feel the pain when I'm playing with my first and second fingers.
I'm not sure whether this is just a muscular soreness from the heavy rehearsal the night before or the beginnings of tendinitis and I should get it checked out.
Let's hope you have not seriously iinjured yourself to the point of tendonitis. It sounds as if you simply over-did it a bit. Take some time off and see if the pain subsides. Now: I have no students in, no do I have
pain from playing. One thing you must assess (find this in other threads) is the amount of energy you use, supporting what kind of form. Almost always, rounded forms (fingers, arms, wrists, elbows, shoulders, etc) are most efficient. So, be sure you are playing with rounded fingers, do not lift too far from the fingerboard, do not "open" the hand or straighten fingers when lifting from the fb, use as little "squeeze" as necessary to get the "forte" sound (whether the bow or pizz is pp or ff) - which, btw, is different on every string and note.
It sounds to me like you need to assess the forms you are using, the angles of approach to the instrument, and how much straightening or lifting you are doing.
Best to you!
