I had surgery 01/03/14 on my left shoulder
Mine was called a S.L.A.P. repair, "Shoulder, Labrum, Anterior & Posterior". The surgery was no big deal, I slept right through it. It is outpatient surgery, mine was 3.5 miles from home. I later went for Physical Terrorpy twice a week at the same complex.
My shoulder was taped to my body for ten days, the arm was in a sling. I was given about a dozen truly powerful pain pills to take the first few days, and really had no pain to speak of during that time. Don't wash the pain pills down with a Foster's...maybe not with other brands of beer either. After that period, I did experience pain but laid off the pills. Pills of lesser strength did not help much with the pain, I just didn't care. So I stopped taking them.
Physical therapy brings on more pain, but is necessary. It is the key to returning to your former self. Go to P.T. religiously, do your exercises at home, don't do anything stupid to damage the arm. Your age and health will affect your recovery.
Buy a few shirts that are a size bigger, they are easier to put on and get off. Practice putting your socks on with one hand. You likely will not sleep well, some folks sleep in their recliner chairs. Buy a few small pillows to use to support your arm when you sit or lay down. Buy a few hand towels and a pair or two of tube socks, roll the towels up and stuff them in the socks and place these between your body and arm to ease the tension on your shoulder when you are up, and later when you exercise with the various strength rubber tubing the physical therapist will give you.
Know that success will not come overnight but gradually. My range of motion has fully returned but the strength in my left arm is best below shoulder height.
I am 57 years old, non-smoker, hardly drink alcohol, maybe 20# overweight, if this info helps you.
I work for the USPS and was out for 10.5 months. Good luck to you.
