Hey Ann
For me I am staying in a room by myself (most of the time)down here in Perth so it is a bit easier for me with privacy. But a few minutes a few times a day would be fine or just when you get a chance to have some privacy.
I originally started doing it when I put the cream on, I would lay down with treated area arm up over my head resting on the pillow. That allowed the cream to dry, not get on your clothes and to allow some air to the area. I feel that when we get hot and sweaty and the creases get wet and sticky it gives more chance for blisters etc. to form.
It is like everything I guess in that what works for one might not work for another. I have only 5 booster zaps to go and I am feeling good still about my radiotherapy (touch wood). Whether what I am doing works, whether it is my skin type, cream type, good radiotherapists, the fact I still have a breast to protect the area so more padding for the rays to get through and not direct on the chest wall. There is a lot of things to take in to account I think.
When are you starting your radiotherapy Ann? I hope you are doing okay with the chemo and not too many side effects.
I am looking forward to getting back home at end of next week. yipppeeeee
LOL, take care, Mich xoxoxo
