The interesting thing about these sorts of injuries (and more in general, excess stress in your muscles) is that we always talk about playing with no stress, using as little effort as possible.  This is of course completely correct, but it doesn't give the prescription for being able to do this.  If I may, I'd like to tell a story.

One of the things people tell me when I play guitar is that I make things look effortless.  That's not a boast, that's the result of doing it for many years.  Decades.  My muscles are so accustomed to playing guitar that I can do it will very little stress and muscle tension.  A new player will always have more tension, because the muscles and tendons are not accustomed to the motions.  I used to tell students (and I am ashamed of this) to practice using the least tension possible, as if they could tell.  The reality is that new motions will create excess tension because your muscles are not attuned to the motion yet.  The best advice that I've been able to give is to break up your practice time into shorter chunks, like 15 minutes at a time.  Eventually, given that you know you should use as little effort as possible, your body will learn the motions and start using less effort.  That is the time when the "traditional" advice starts to become useful.  If you have pain, back off.  Wait for a week.  Try again.  If you still have pain, back off for another week.  Once you can play without pain, play for 10 minutes, tops.  Rest for at least 30 minutes before playing again.  Then play for 5 minutes.  Do not "practice through the pain."

You will most certainly enjoy playing the violin for many years if you make sure to get through the early stages without hurting yourself.  It is best to back off and make sure your body is working properly before you start to push yourself.  Many practice sessions of 5 minutes each may work better than on practice session of an hour.  Never measure yourself by how long you can practice in a single stretch.  That way be dragons.

Best of luck to you!
