Well I dont know about candida. Did you see a naturopath who Identified candida?
From your symptoms:
-Dizziness
-Mental fog
-Body rashes
-Headaches
-Feeling faint
-Vibrating in back, head and ears, especially mornings and nights
-Sore/tight throat and neck
-Swollen glands in neck I can tell
I would think of adrenal fatigue because of the dizziness - especially so if you feel dizzy when you get up too fast.
Are you bloated and do you get pain in the gut? That would complete the picture to aim at candida - but these symptoms above are so wide - they definitely point to a immune disorder, yet which one?
