Hi Angie,
I had 20 sessions of Radiation to my breast 13mths ago.
I used Sorbolene in the lead up to, during & after Radiation therapy.
No side effects for the first 2 weeks - by the 3rd week there was some pinkness over the entire breast & an ongoing internal itch deep inside the breast - that drove me crazy!. Oncologist prescribed an ointment for the itch which helped.
The pinkness & itchiness subsided soon after treatment. Experienced strong twinges (feels like an electric shock) in the treated breast for a good few months & the skin on my treated breast & nipple peeled a few weeks post treatment too.
Hope that helps & all the best with your remaining treatment :)
