If Linda isn't pregnant or hasn't recently given birth, she shouldn't be making milk. Abnormal colors in the discharge could indicate infection or inflammation in the gland. The only way to know what a lump is caused by is to take a sample for examination under a microscope or submit a biopsy to a pathologist. I would recommend having Linda re-examined by the vet with this new information or get a second opinion.

Unfortunately, the pictures are not clear so I cannot give you details on what it looks like and the videos do not work on this forum. It sounds like she could have an infection in her mammary tissues or possibly some other type of infection. I would strongly recommend to have her seen by your vet as she likely needs antibiotics to prevent her from becoming septic. I hope this helps!
