@celia16 thank you Celia16. Good to know you're here and have some reassuring information. But I do have more systematic effects than documented, chemical sensitivity could be part issue, and I've read damaged radiation tissues have increased uptake of RX, or "drink" more of the RX. I think swe.ling breasts are a basic sign of some uptake, along with spinal or vertebral discomfort or pain - back pain is fairly common.
Some women say more irritating effects can subside with longer use - getting used to new drug.
