Well, Howdy, Mimi, I'm MimiTabby and I ride a used Bianchi Veloce too

The Veloce is a really good bike, with good componentry and before you dump
it and go and buy yet another bike, take your Veloce somewhere and get fit to it! It's a lot cheaper than buying another bike. (Unless you have lots of money that is and cost isn't an issue)
It's taken me almost a year to feel comfortable on a road bike after riding the hybrid type before, so give yourself more time. But PAIN, get that checked out!

Go to a shop that does fit, be prepared to spend about $100 (or even a little more) for the fit plus parts if they have to change anything.

and welcome to TE!
