Radiation therapy vs nail insertion

I had radiotherapy after surgery on my left breast and armpit.Did not find it too bad - was expecting big skin problems as am very fair plus area treated over my heart. Do feel the odd twinge since it finished but onc said is normal and did have a red hot breast for a while but not unmanageable.No lymphodoema as yet. Have been creaming the area 3 times a day for nearly 3 months now which gets tiresome and mucks up my underwear - I use Dermaveen . Did get drowned in tiredness the week after it ended but otherwise ok.Oh and daily trips to get zapped can get a bit much - appointment time varying across the week , trying to find a park , up and back daily.Do I regret it - no - went past in bit of a blur tbh.Am retired but very busy family life with 3 kids coming and going plus volunteer work but didn't miss a beat.Was a bit cushioned though as those around knew my situation.
