Female 54 -4 Weeks Ago Lifting 12lb Arm Weights I

Female 54 -4 weeks ago lifting 12lb arm weights I pulled or hurt something in my shoulder. I have pain at times from my shoulder to my elbow. I noticed a bruise from on the outside of my upper arm 4" h and est 4" wide. It is taking a long time to get better with icing and anti inflammatory drugs and it twinges at night. Should I see an orthopedic Dr or will my arm time a while longer to heal!
