I did not have a port. chemo nurses told me about drinking more water before an infusion which helped although still don't like have blood taken much less the 18m of infusions I hope never to have again. Veins at elbow were shot before 2 nd chemo but able to have infusions all the way.
Had some trouble with blood being taken from hand after chemo finished mainly being a problem from unsympathetic "vampire ladies" for annual bloods but after 5 or more years now all ok and can have blood tests from my elbow again.
Hope all goes well for the remainder of your journey.
It does get better - although fear of getting a reurrence or new primary does not at least not for me - just learn to get on with life.
One garden show 10 houses around a private school today and more orchid shows and spring fairs this weekend after voting for me.
Its such a glorious warm sunny spring this year.
