Hello mrsD,
I'm not taking the Rx version.otc version. So then I need to take 3 a day every day. My D-400 and my calcium is 600. So I calculate that I should take both of them 3 x a day to get 3000IU. I tryed the Lidoderm patches with and it didn't help. I do however have the skin burning going on in my legs, hips,back and groin. That is why doc G has me on Lyrica. This is helping to some degree, but my legs feel like I ran a 1000 mile marathon everyday. My legs feel like they can't hold me up and my back is the same. I can only hold my head up for 2-4 hrs a day because of the neck surgery. I loose feeling in my feet alot and my hands.I will ask Doc G about the B12 and A1C report. My nerve pain is due to the herniation @ S1-L5. Yikes ! It also effects my feeling in my feet and groin area and going to the bathroom. Gee, I feel old ! lol Thanks again for responding to my post.
