For the past 2 years I have had a small, movable knot in my left armpit. It is always a little sore if I press on it, but during my period it is painful just to move my arm. Not horrible, but there is tenderness there. I have seen a surgeon twice and my gynecologist twice. I have had 2 ultrasounds and 2 mammograms over the past 2 years. The results have been that it is a swollen lymph node with no explanation about the reason it is swollen beyond, "It's hormones."
I went to my general practitioner last week and told him that the lump/knot was still there and that I have a burning sensation on the inside of my arm from my armpit to my elbow and also a burning pain on my left shoulder blade. He decided to send me to a neurologist since he thinks it's nerve related.
The neurologist feels of the knot and says, "That's not a lymph node. That's a tendon. That's the bicep brachii tendon."
So... is it a tendon? Is it a lymph node?? Oh the humanity!!!
