I have a swollen vein in my left armpit. When I raise hand you can see it without touching. It is somehwat painful, tender and sensitive to tuch. I've had a lumpectomy (carcinoma in situ) 9 years ago. Have had mammograms and ultrasounds twice per year for about 6yrs then scheduled for once per year. Had mammo last December; radiologist said I didn't need an ultrasound since everything wa fine. This July I've found the swollen vein. I've had an ultrasound of the arm, CT scan of chest, xray, and blood work done at the ER on Jul 27. I was told everything was fine. However, I'm still concerned. There is also swelling on the inner side of my elbow. Not painful.
