My dad just had his second shoulder replacement within one year. He tore up his shoulder after the first one by pushing to hard to fast. He almost damaged it to the point of no repair. Please strictly follow the recommendation of your doctor and physical therapist. Due to the damage he caused after his first surgery, he may never be able to golf or play baseball again. On a good note, he already has more vertical range of motion than he has had for probably 20 - 30 years. Good luck and God bless.
