gem/carbo and rads

I’ve now had my 3rd cycle of gem/carbo yesterday and had rads to my left hip and right shoulder blade the day before. This morning when I ventually got dressed at 1030am , my right breast was all red and swollen, my left side where I had my mastectomy and rads and my shoulder blade were all bright red as was my left arm with lymphoedema. I had to go to the hospital with my 7 yr old anyway so saw a onc doctor but not a breast one but one who specialises in abdo cancers!!
She did a full blood test which showed nothing unusual for me but did not do blood cultures from my long line where it looked gungy and red. Came home with more fluclox ut am reluctant to take it as only finished 4th course in last 3 months so though I would wait and see what long line looked in the morning. I know i’m probably riskimg it but don’t feel ill today but felt fluey yesterday evening. This happened to me with taxotere and rads so feel happy it is an allergic reaction.
Will keep you informed but has this happened to anyone else -will also post this in secondary forum.
Thanks
Kate
