What tests (blood or other) should I nake sure are done?
If this is not MS, what else could it be?
Thanks.

It's true. Some research suggests that you need in excess of 40,000iU/day. I get vitamin D added to any blood tests that the doctor orders though and I'm not overdoing it yet..Just_Me wrote:Vit D is one of the vitamins that you can get too much of (D,E,A & K), so find out what the symptoms of ODing are and watch yourself
