pain traveling down my leg - should I be worried??

Hi all,

am half way through chemo have had 4 epi and one cycle of cmf. I had a ct scan on tuesday with contrast and have a hickman in on the right side. for the past few days my leg started to hurt (right one). the pain was high up and over the last few days it went to my knee and now my ankle. the veins are raised in the areas it hurts and the pain stings. should I worry?

I am a little reluctant to phone hospital as had two admissions already and dread them saying to come in!!!
