Had minor then sever pain i. shoulder. er put me in a sling saying strain. week later movements still painful. ?

Time for evaluation: Shoulders can take some time to heal. You want to move it some to keep it from freezing up making it very tight and stiff. If you have waited a week and it is not getting any better you should see a physician to see what is wrong and to make sure it is OK to move it around. Physical therapy can help but see your doctor first.
