If you've got a digestive problem since you said you had many bowel movements I would check into whether you have IBD as the source of your problems. If you do have this problem it can be the root of all your other physical problems. I have IBD and now have numb feet and a bit in my hands too. I have been taking 2000 IU of Vit D3 per day and still my Vit D levels are too low!! I have been to many Gastroenterologists over the years and none have mentioned this.....the other day I was at the bookstore and read in a book there that "those with digestive problems (ie. Crohn's etc.) do not absorb Vitamin D readily because of the inflamation and should lay under tanning lights that are UVB type so that they will be able to obtain sufficient levels of Vitamin D!" I could'nt believe what I was reading actually and was shocked to read it especially after suffering for this long with numbness of the extremities! (1 1/2 years now!) So Gastroenterologists don't seem to know or care that their patients are deficient nutritionally, and they just say, "Ahhh, duhhh????!" when asked what is wrong with one's body! I once read that Vitamin D should actually be called "The Master Hormone", because it controls so many processes in the body! It may even be the reason why people have MS! I say that because most MS cases are found in areas North of the Equator where sunshine levels are low. I hope this helps you in some way to get back to normal!
