Shoulder pain when walking

I have severe pain on top of my right shoulder after only one or two minutes walking. I stop and it is relieved. Start again and it returns. I am 70, please suggest the possible cause of this problem. Thank you.

That's pretty hard to explain, i'd see my doctor to examine my shoulder

it could be rotator cuff strain or acromioclavicular joint separation
