Low vitamin d, CIN 1, lump in armpit, fatigue, weight loss, Breast pain and recently had an abscess removed from Breast near nipple, cause?

See MD. You should see the same MD who removed the abscess and if the lump in your armpit is on the same side as the abscess, this would make sense, because the lymphatics drain that area toward the armpit on the same side. You should see the doctor and may need antibiotics.
