Hi everyone, my little one is seven months and getting heavier by the day, so I don't know if this is something to do with it, but for the past six weeks or so, I've been waking up with neck pain on my left side. I don't know if the fact I also sleep on flat pillows anything to do with it. It clears up once I'm up really, but just wanted to see if anyone else had suffered with this postpartum. I've tension in my shoulders and the stiffness is left hand side neck and up as far as behind ear. Thanks
