That's exactly what it sounds like and it SUCKS. I had it start about 2 weeks ago and it's so so bad right now, you're lucky you should have your baby soon.
I've done acupuncture and chiropractic both and it really doesn't help that much. You can sleep in wrist splints but those are uncomfortable too. Honestly the best cure is for our babies to get their little butts here!! I had it to a lesser extent with my last pregnancy and was amazed that within hours the swelling in my hands had gone down to basically nothing. Hoping for the same miracle this time.
