Swelling towards the end of pregnancy?

Miranda
I'm at 35 weeks on Sunday, and for the last few months I've been going crazy with massive swelling on my feet and legs. Now I've started scratching because it hurts so badly! I have no signs of preclampsia but wondering if anyone else is going through this and found a way to relieve some of the swelling? I now have carpal tunnel in both wrists too- please tell me this goes away :(
