Some years ago I too developed intermittent breast pain, then eventually it became a constant pain and tenderness.
It would sometimes ease off when I began cleansing but it wasnt until I started to do parasite cleansing properly, eg: with 90 day gaps between cleanses that the pain went!
In fact it went after a parasite cleanse I did earlier this year, just before I discovered Humaworm, but it returned, but after my first round of Humaworm, the pain had gone and has NOT returned, not once not even a twinge!!
That was May/June time.
It is my thinking that it was parasites, not sure which, but definitely parasites!
