For the past couple of months, my left breast has been itching on the bottom side near the bra line. It drives me crazy. I looked online and found out that there are some types of breast cancer that itching is a symptom. It isn't red and there is no discharge. Yesterday I noticed that there are some small bumps. Almost like a rash. I have not been having this. I have also had some problems with my knees and elbows itching. I do not have dry skin. Is this some type of allergic reaction or should I be more concerned? I feel weird about going to the doctor and telling them my breast itches. It sounds crazy.
