Have you ever been to a chiropractor?
I've seen mine almost every week since my first trimester. He's fantastic and not only makes my back and shoulders feel better, but if I'm having trouble stretching, he'll do that as well.
@socalleslie25, I hope so! I feel like I just want to crack my back and lay down all the time
Stretches me out, cracks my back. My left shoulder has been a problem for me, so he works out the links there. I wasn't able to do basic movements, think swimming movement, but my range has gotten better. He's also stretching out my hips right now to get me ready for baby!
Find one who works with pregnant women, they have special pillows that will allow you to lay on your tummy (and you can buy them online starting at about $300). Get a list from your insurance and start calling.
