Protecting body from radiotherapy

I am at 26/30 treatments of radiotherapy. Have not been able to wear a bra at all since week 2!  Moo Goo 4 times a day. Bepanthan cream twice a day, I mix the creams together... Then for a few days I also needed Lignocaine for the pain. The nurses have been brilliant and although I have had a “ decent” reaction they are impressed with my self care. That made me feel good! 
I have also had lethargy...big time. But nothing I have experienced is new. As you have read by now we all have different reactions etc.  I have struggled big time with the heat also. Anyway, I’m nearly there and wish you all the very best @Pookie
