I'm no Doc but I have lots of experience with nerve damage in my shoulder. If that's what Pedro has it could be bad news.
I had a mountain bike crash many years ago that resulted in a torn accessory nerve. This resulted in electrical impulses to my trapezius muscle being short circuited. Since the trap wasn't getting any signals it atrophied and my scapula started to wing (basically rotate off it's vertical axis) when I extended my arm. This caused all kinds of instability and ended my days as a rock climber. And the muthfkr hurt all the time when I used it,tingling and numbness in my hand. Doc's said surgery was a long shot and the best bet was rehab and strength building. This took years and it still hain't right.
Your shoulder/arm is the only part of your body that has 360 degrees of rotational motion and is one complex MOFO.
Bad place to have nerve damage
