I’m ctually from the Auto immune community but felt compelled to write in the Back and neck community. My Rheumatologist checked my Vitamin D levels and anything under 32 is considered dangerous. Mine came back a 7.5. I was put on 50,000 iu’s of Vitamin D a day this is prescription only, they said it was so low that normal vitamins would not help. I’m amazed that my back problems have gone away. I always though it was just something that I would have to live with. I’m writing to your community to ask people to have the test run, I was amazed to find out that its not just a test that is ran automatically. There are many reasons why you may loose your vitamin D levels. I have not felt this good since I was in my 20’s and just wanted to let you all know They are finding that low vitamin d levels contribute to several diseases such as Cancer, Multiple Sclerosis, Parkinson, Rheumatoid Arthritis. I hope this helps others. I’m so amazed in the difference that I feel.
