Thyroid/Hashimoto's?

My mom is a 45 year old women who has hashimoto’s thyroid disease. The doctors found a nodule with undefined boarders. She is in so much pain and her neck feels very full her left side. During this she has been unsuccessful finding a good doctor that understands what she is going through. Now she has developed another thyroid nodule on the other side of her neck. Her neck is very tender to touch as well. She is very weak and tired. What do you think is going on? What have you done to get control your hashmotos? Do you know anyone who has hashi’s? Anybody have their thyroid removed? Any Info you can give me will be helpful, Thanks so much in advance.
