I'm just under 14 weeks and this morning developed extreme pins and needles in my feet and then a feeling of numbness. One arm also feels very numb. And my lower back is starting to be numb too. What could this be? DH is away at the moment so I'm doing all the dog walking - about 2 hours a day. It isn't usually a problem but yesterday and today my hips hurt when I was walking - could that have something to do with it? I'm at work now and just can't get comfortable. Really don't like the numb feeling. Surely the baby isn't big enough to cause this by sitting on a nerve??
