They found a 6mm nodule on my thyroid when they did a C-Spine MRI. Just wondering what it means. I have RA, Fibro, IBS, DDD, Chronic pain, I have recently been having alot of pain on my jaw, ear and neck. It really bothers me like when you try to rest your chin in your hand. I am 53 yrs. old and just have alot of health issues.
