Hi! My neurologist suggested that I start on vitamin D 5000/day. I did and felt fine. It was about a week later I got these really sharp pains in my bladder/ low ab area and sharp pains when I urinated. I thought it was a uti but the culture was negative. Talking to my gyno today, she says perhaps it was the passing of a small kidney stone that made its way to my urethra. I read that kidney stones are mostly calcium stones and one of the cause can be hig doses of vitamin D. Wow. I’m no dr. But it did raise an eyebrow. Even before I knew this I have gotten lazy with my vitamin D but now I’m hesitant. Anyway I’m going to run this by my neurologist, I just wanted to bring it here to see if anyone else has had anything similar. I know the research on vitamin D and MS and I really do want to keep with it!
