Thanks S001 for this thread.
I also have the same problem when it comes to needle pricks.
The nurses always have problem finding my vein to take blood for cbc.
They complained my veins are too fine.
The process always take longer time then others.
I'm scared as its quite painful & I do get a patch of bruise after that (maybe cos of my low platelets??) & takes weeks to heal.
Maybe the next round I try the warm blanket or sweater as suggested by riccd2001. Thanks.
