Question about relaxin?

I'm a little over 3 months pregnant, and IT'S KICKING MY !! It started very early for me (around 4 weeks), and I was just wondering, is it normal for it to affect other parts of your body other than the hips and pelvis? Man, I'm ok as long as I'm up walking around, though my pelvis gets a little sore, but geez, when I try to get up after sitting down, or up and down stairs, it's killer. I have 6 more months to go! Is there any way to make it better?? Maybe it will calm down after I get into the second trimester?
