I developed a swelling in my neck. Doctor said I have a diffuse goitre and is sending me for ultra sound. My thyroid results doctor said were very slightly borderline low T4. I also have CFS/ME and Candida as well as advanced periodontal disease. I have been trying to treat my Candida eating garlic. Any one familiar with Candida will know about die off. I am really scared because as the Candida dies off my goitre gets bigger. Could anyone explain this ? I am trying to help my body get rid of candida but making the goitre worse. Doctor says I have auto immune thyroid. Sorry it's all very new.
