Cazl, I only have the one biggish blister that I can see, huge red area and very dark and quite painful under arm and moving onto the chest. As with all of this, we are all unique so no one can tell us what 'normal' really is. I am experimenting with some different creams mentioned above to see what gives me relief, so far the winner is the B (something) Soothing Cream in the blue box. My two weeks is up so I am looking forward to less discomfort. Something good is that next week is student free at school so if I feel up to going in, I will be able to go bra less!!!!! Well, perhaps not. Bigger things to worry about, another scan today and blood tests then see oncologist Monday, so I need to put this into
