Hi R.
I am a physical therapist. I had carpal tunnel with my pregnancy also, but only numbness in my hands. This condition is not caused by the baby pushing on your nerves. It is caused from a combination of swelling and laxity in your joints that encrouch on a canal that runs through your wrist. Unfortunately if the nerve is also being pinched in your neck, secondary to muscle tightness, posture or laxity in the joints you get a "double crush injury" to that nerve and it causes problems all the way down your arm. One of the simplest treatments that helps some of my patients is ice. Ice at your wrist and possibly even at your neck and shoulder on that side (or both if both are hurting) Ice for 10-15 minutes a couple times a day. When I told my Dr that I was getting carpel tunnel during my pregnancy, but was icing a couple times a day. She asked "does that work, I never thought to tell my patients that" A lot of Dr just chalk it up to normal complications with pregnancy and it will go away. If you need more help, I suggest getting a referral for physical therapy to help assess for any postural issues,and or muscular tightness. This condition can also cause muscle cramping. However, so can an electrolyte imbalance. Make sure you are taking in enough water, calcium and potassium. I hope this helps and I wish you lots of luck
