Ribociclib, lymphodema and blood tests

Hi All

I developed lymphodema in my right arm during radiotherapy. I’m starting on ribociclib next week and know it involves lots of blood tests. I have poor veins so I’m worried about numerous needles in one arm. It’s going to get very painful. The anaesthetist took 3 goes and she does it all the time! Does anyone have experience of using an arm with lymphodema for blood tests?
