If you are not getting relief for your painful breasts from Iodine alone, you may need the low oxalate diet. I have fibrocystic disease. Iodine alone wasn't enough to resolve the pain & tenderness I had in my breasts. I didn't get significant relief until I went on the low oxalate diet.
Oxalic acid (and oxalate compounds)are chemicals found in all plants. Some plants have more than others. When oxalic acid combines with minerals such as calcium, magnesium, etc. it forms little crystals with sharp pointy corners. In susceptible people these crystals can accumulate in the tissues of the breasts, old injuries, joints, kidneys, gut, genitals, skin, etc. Oxalates seem to be attracted to areas of inflammation and they cause additional inflammation and the release of histamine. Oxalates crystal accummulation can make you miserable!
I got rid of the pain in my fibrocyctis breasts ONLY after following the low oxalate diet for six weeks. Iodine alone wasn't enough for me.
