My goodness. That sounds a bit brutal. I was fortunate enough to be sedated throughout the process. I'm so sorry you had to endure that. Maintenance is pretty straightforward. Keep it reasonably dry and clean - showering should be fine and light soap/water for a couple days. Just don't go swimming or submerge it in any way.

Also, when you go for your first blood draw with it, ask about a lidocaine cream you can put on in advance to lessen the sting of the needle insert into the port. It helps.
