In some cases, these two problems that are co-morbid to thyroid disorders can coexist, so that they are occurring at the same time and this may be referred to as “neuromuscular disease”. This is a symptom-aspect that has less information available on it via online medical search, than do the more common thyroid-related problems, such as weight gain, joint pain and fatigue. Within the chapters of this book, that follow, I hope to present to the reader, a general understanding of these often debilitating and potentially very serious manifestations of thyroid disease, affecting the nerves and muscles of the body, including the treatments available for them. I present this information to you as a fellow hypothyroid patient with autoimmune thyroiditis and co-morbid peripheral neuropathy and myopathy, which inspired me to search and research the information contained in the chapters. NOTE: This ebook is not an extensive medical journal but rather contains aspects of information on the subject that most laypersons would be seeking. CONTENTS:
