Since birth of my first child seven months ago I have had pain and coldness in lower legs. I had a normal pregnancy and vaginal birth with no drugs. Any idea what this could be?

Possibly sciatica caused by abnormal stress against the uterine wall, which then presses against the sciatic nerve. Although you have already delivered the child you may have aggravated the sciatic nerve pain stemming form the pregnancy. Also, it could be remnants of gestational diabetes brought about by pregnancy. The possibilities are endless. I recommend you see a physician.

I recommend you see a chiropractor. The normal low back stresses that occur as a part of pregnancy and childbirth may well have aggravated a pre-existing low back misalignment. I recommend an hio method chiropractor. ( the preceding for entertainment purposes only).
