Torn trapezius...went to emergency room

Last Sunday (one week ago) I was doing chest in the gym.  I think it was either benching or weighted dips that did it.  The next day after my workout the pain started to come on.  By day two I couln't get out of bed.  I can not move my neck in any direction and have extreme pain in my left trap/neck area.  6 days after the injury and realizing that it's only getting worst I decided to go to the E.R.  They prescribed me meds for the pain, told me not to lift, and to follow up with an orthopedic on monday.  Has anyone ever experienced this injury?  If so, what kind of recovery time am I looking at.  I hear surgury might be nessesary if the tear is very bad.
