I have been having very bad headaches the last few days. Not normal for me. I had a concussion from a fall on March 17. Was checked out and everything seemed OK. Wondering if symptoms could be starting now? I have also been preparing for some other tests due to my hypothyroidism and adrenal fatigue. I have gone off all of my supplements which included vitamin B, folinic plus, vitamin D, malic acid, and magnesium. Wondering if it could be from not taking my supplements?
