Vitamin D supplement (2000 IU) gives me an intense burning sensation in my head accompanied by anhedonia, depression, worsened blunted affect, joint/muscle pain and general physical and mental fatigue. General flu-like symptoms are also present (runny nose, malaise, etc.).
CoQ10, creatine monohydrate, and glutamine also give me a similar reaction. High dose vitamin C also triggers it occasionally.
I suspected having an autoimmune disorder in the past but antinuclear antibody test (ANA) was negative. ESR was slightly elevated but my physician said it wasn't significant. CRP was normal. EEG and MRI are normal. Hormones are normal. My physician doesn't know where to go from here so he simply brushed it off as being psychogenic. My psychiatrist disagrees with him.
The head burning sensation is relieved by benzos and, to some degree, by NAC. Caffeine makes it much, much worse - I avoid it like the plague. Also, I tried Levodopa/Carbidopa in the past for anhedonia, but it gave me an even more INTENSE head burning sensation and the same symptoms as above.
It seems to be related to dopamine, glutamate, immunity and mitochondria. Perhaps even a latent infection. Any ideas on how to proceed from here?
