Three weeks? You got off light. When I tore my RC in '99, I couldn't move my elbow more than 3 inches away from my rib cage in any direction. That's how immobilized my shoulder felt. Unfortunately, I also broke 3 ribs in the same fall, and that pain was so horrendous that I didn't realize the shoulder was injured until six weeks later. Finally had the surgery nine weeks after the original date of injury, and was on the shelf for four more months.
Crawford was talking about his injury the other day to Brad Sham and Babe, and he said he couldn't raise his arm enough to brush his teeth with his normal hand. I can sympathize, but he's gonna find out that the rehab is more frustrating than it is painful. It's a "right-handed" world we live in. I drove a stick-shift... Sort of. My daughter actually did the shifting while I depressed the clutch. The best part, however, was going to the bathroom - especially at night. I had to sleep in the recliner the first month post-surgery, due to the pain sleeping on my back caused. Well, just where is the lever on the lay-z-boy? On the right side, of course. There were times I had to yell across the house and hope someone heard me before I wet myself. Seriously, I was worthless. You've heard the term "right-hand dominant"? Well, I'm "left-hand ********".
It's been 16 years since my surgery, and I never regained full range of motion. Good luck to Crawford in his recovery. I'm sure he'll be back with a vengeance next year.
