My right side collarbone is much larger than my left
Below my right ear and above my collarbone, I have a cyst, seems to be really mushy, about the size of a tennis ball. It seems to be smaller when I wake and gets larger in the evening. I have pain, tingling, in my shoulder blades, (mostly right one), throbbing pain across my shouders and right elbow down to the middle finger.

My doctor says he does not believe it is a lymph node, but possibly a swollen bursa sac. No other symptoms at all besides what seems to be arthritis in the shoulder blade, possible a pinched nerve somewhere.

Help worried sick it is breast cancer. My father died of bone cancer and my sister had breast cancer.
