My
Vitamin D level is 22. Other things normal. For the past few days I am unable to sit and concentrate on computer. Feel as if I am about to fall/imbalance. Can it be due to low Vitamin D level or something else. Sometimes I also have back ache (while sitting, standing and changing positions). Also having straightening of cervical spine due to muscular spasm. Please advise. Is there need of x-ray spine/back, CT scan or MRI etc.
