I am 22 year old female and have been diagnosed with Vitamin D deficiency (16). It started off 6 months ago with constant head tingling that went away and reappeared 3 months, I have head tingling in my knees, and feet. I began taking D3 a month ago and the tingling has gone away, but I have constant chest pain, brain fog, jaw pain, and headaches. I have had a brain MRI, a chest x-ray, EKG, and blood work and seem to be perfectly healthy. While I feel somewhat relieved that its just a vitamin d deficiency I get scared thinking it could be something else as I can't believe that being deficient in vitamin d could take such a toll on my body/anyone's body. I just want to feel normal. Any advice and support would be greatly appreciated.
