I had labrum surgery in August of 2003....I was in an immobilizer for 3 weeks, followed by a sling for 2 weeks...I wasn't able to move it past 45 degress for another month...Just a FYI for the shooting LH...However, I was being very cautious while rehabbing to be ready for spring baseball...
Now, I ended up tearing it again the next spring (~March 04) after 4 months of rehab and easing back into throwing/hitting...No 2nd surgery and been used to the pain for years...
So, summing up my

...If you do have surgery, I would be take care of it for a good 6 months to let it completely heal...if not, you too could possibly be on the road of learning to deal with the pain or surgery #2....
