Wow you certainly have had a tough time @manzganz. I had big recoveries from multiple surgeries over several years. It does take time to get over all the wounds and anaesthetics etc. I had chemo, radium and now hormone blockers. My cancer surgery was in 2020 and so too radium and chemo. I had 2 more surgeries related to my breast cancer in 2021. I started the hormone blockers in November 2020.
Radium was a little easier for me than chemo. Talk to your breast care nurse about mepilex or the cream that can be used on that radium area to minimise any discomfort. Drink lots of water too and if you are up to it do some gentle walking. It all helps. I had 4 weeks of radium and I did get a couple of areas that were more red that the rest. One area that was a little painful was where my lymph node removal scar was. I guess it is a very tender area of the body so take care of the scar lines.
In terms of hormone blockers some people have no problems with side effects so hopefully you are lucky there. I started on tamoxifen and was going well for 18 months and then experienced some side effects so my oncologist changed me to Letrozole and I have been ok since then. My message there is always let your dr know any issues because you don't need to suffer and there are other options.
Good luck with your radium treatment. I hope it goes really well for you.
