I have been working out for almost 20 years now. I'm close to 46 years old. When doing flies 2 weeks ago, I upped my dumbbell weights to 20lbs each. (Not the first time, but the first time in a couple of months.) I'm very careful about a good sore and a bad sore feeling when I lift and I felt something in between. Next day my left shoulder was uncomfortable, but not "painful". I stopped exercising and decided I would let my shoulder rest, and start back up when the discomfort eased up. This was on Mon. By Sat night I was in the emergency room with EXTEME pain in my shoulder. They gave me painkillers and said see my pcp. Went to see him and he referred me to an orthopedic surgeon. Went to see him and he scolded me for using such a heavy weight. He said women my age should be working more on flexibility and endurance. I agree those 2 things are important but what I don't understand is since I've been lifting for a long time, why shouldn't I continue? (This is of course when this dang shoulder heals. I don't have a problem easing up on the lbs for lifting either.) I never want to experience this experience again, so you better believe I'll be very careful in how heavy I go in the future. It's funny because with all the running and step I do, you'd think I'd have knee problems first. But now I'm thinking that may be right around the corner. I'm not being paranoid, really. I'm just very discouraged with what happened and what the doctor has said to me. Any advice? As women age do we need to be more careful about the stress we put on our bodies? (BTW, even though I "feel" like an older woman today, doesn't mean I think of myself older at age 46 I'm just repeating what the doctor said.) Thanks for any help!
