I have had a strange development and I wanted to get opinions. I have a area on the inner aspect of my right arm, just above the bend of my elbow. It is about an inch in diameter. It is not red, nor hot, nor painful. It appeared within 24 hours of me starting the Biaxin. (Which by the way seems to be helping somewhat.) I am sure this is probably Lymph nodes. Has anyone else developed any lymph node swelling during treatment? Thanks in advance.
