Currently I am taking B12 for low B12 as well as having low Vit D. Ive been having difficulty finding a diagnosis and my health has been declining steadily. I have major pain in my kidney area, occasional headaches, kidney stones, I also have extreme fatigue. My newest troubling symptom has been this rash that looks like stretch marks on the left side of my back and my left buttock. Also started to get vilitgo on my groin and right elbow. I am a 24 year old male and I am desperately looking for a diagnosis.
