It is difficult to say if the pains you are describing have anything to do with the mass in your breast unless I could know for certain that it were a cyst. If that is the case then, I would be more likely to say that your pains are unrelated to the breast cyst. If the lump is not a cyst then, I'd need to know what the lesion is from a pathological perspective and then, you may need other imaging studies to define what was going on in the neck and shoulder.
