How can I relieve my hysterosalpingography (hsg) worries?

What worries? Worried about discomfort or getting bad news? Talk with your doctor is a good start either way. I personally do up to 5-6 hsgs a week: all women dislike it, but 99% say it's not much different than having a pap (but that's my personal experience.) reading scare stories on the internet is one of the least helpful thigns you can do! good luck, you'll do fine.
