A visit to the GP and then a visit to a Physio may help, especially if it is posture related...….we tend to favour a certain side, without realising as we protect the breast. I wasn't far off a frozen shoulder apparently by the time I gave in and went to the Physio; I didn't want anyone to touch anything as I became so overly protective. I couldn't raise my arm up my back and that was the trigger for me as I thought all the aches, and to a certain degree I was correct to think that, were directly related to surgery.
Take care
