Hi my email address is YYYY@YYYY . I have been experiencing EXTREME fatigue for the past year and have recently seen an endocrinologist who ran some blood tests on my thyroid and said everything came back normal...after I insisted upon it he did an ultrasound of my thyroid because I have had a lump there for about 5 months. They did find a nodule on my lymph node but the biopsies came back fine. I have so many other symptoms like insomnia, intolerance to cold, memory loss, weight gain, muscle pain and stiffness......is there anything else you would suggest I try looking into with another doctor or any idea what I might be dealing with here? Desperate for help! Jennifer Thank you for your time.
