I've posted before in regards to breast pain. I had a painful cyst in my breast that wouldn't go away. I remembered that DMSO is a solvent that carries any substance deeply into the tissues and blood. I put a few drops of Lugol's in 2oz of DMSO and rubbed a few drops of the mixture on my breast twice a day. In two days my pain was gone.
You can buy DMSO in any health food store. Make sure to wash your hand and breast before applying. Wash your hand afterwards.
