After my 16 week appt yesterday and almost 2 weeks of a tingly right calf/foot I went to the chiropractor this morning. I wanted to make sure the leg was not a sign of something else and to get my dr approval. My chiropractor (who I have seen for 8 years now fo lower right back pain) did a great job at relieving my calf numbness. Fortunately there is no nerve pain just a tingly calf most of the time! I plan on going every few weeks as preventive care. So if your legs are tingly ladies find a chiro who works with pregnant women for a fix. My chiro doesn't use heat or bio freeze and you don't lay on your belly if you are pregnant . Hope this helps!
