it is time to go back again. your doctor may either aspirate (again) or suggest that you have a surgical procedure to completely remove these painful cysts once and for all.
i had a breast cyst aspirated about 8 months ago. it is back and both breasts are very sore. . when it was aspirated the doctor said he never saw that mush fluid come out of a breast before. it was bloody brown but came back normal. now the cyst is back and very painful.
