i found a lump on the right side of my neck 2 years ago, about 3 mnths ago, the right side of my neck feels very tight sometimes, and its very umcomfortable to where i have to keep my head to the right so it stops. i went to the doctors and had an ultrasound, the lump did not change in size first doctor said it was goiters...so i went to a ear, nose and throat doctor they put a camera up my nose and said everything was great, she said something about multinodular...i told her about my neck, i also feel like i cant swallow and my throat feels like its closing, she said it was prolly acid reflux, or stress...ive also lost 10 pounds in like 2 mnths without trying...what could it be?
