I just wore a black cap when ever I went out. I needed the warmth of it near the shops freezer sections anyway. Honestly I think I am invisible anyway. Not once in two years of going out with only one boob has anyone ever looked or noticed.
Re finding a vein, drink plenty of water a few hours before the infusion. When you get there, walk up the road a bit and back to really get that circulation going. Hit the toilet before you go in and take a vest or a bit of a coat to keep you warm. It does get a little chilly in there after a few hours. Sometimes you get a really good nurse who can find a vein right off and sometimes you get those who can't find one, over and over trying. Just the luck of the draw with that one.
Take someone to sit with you during chemo. You don't have to be a conversationalist with them, they can amuse themselves with a book or something. Its just nice to have the support. <3
