I am concerned for you about your health history. The fact that you have "lumps" on both sides of your thyroid is definitely a concern that should be further investigated with perhaps a biopsy. A blood test may not be enough. You could have a normal thyroid blood test and still be at risk for thyroid cancer.
If your weight loss was not intentional on your part, then I am concerned. I think that you need to pursue this with an endocrinologist that specializes in the thyroid. I would highly recommend that you seek out a physician that will pursue this with you until you have a definitive answer as to the lumps on your thyroid and your other health issues as well.
Certainly an abnormal thyroid can be the source of unexplained weight loss. But anytime there are "nodules" on the thyroid gland, a biopsy should be done to rule out any potential malignancies.
The treatment for a malignancy of the thyroid, is removal of the entire thyroid or just that part that has disease. A daily thyroid hormone pill would then be prescribed to supplement the thyroid hormone that your body is no longer able to produce once the gland is removed.
I hope that I have been of help to you addressing your health concerns. If however you have additional questions feel free to ask. You do not pay for responding to questions that I have asked for clarification.
