My ob/gyn found a lump in my breast that a mammo and ultrasound showed was not a cyst. My ob/gyn told me to call a general surgeon to get a biopsy. The first available appointment isn't until Friday, 4 days away. Tonight I noticed that the skin around the lump is hot and red. Should I call the ob/gyn? Should I call the general surgeon? Should I just wait? Thanks!
