What Are The Symptoms IN DETAIL

I will be going Monday for an ultra sound. My grandma to my fathers side had thyroid cancer in her early thirties but no one can seem to remember what type as her children were very young at the time. It was purely by chance that the Doctor stumbled upon my enlarged thyroid because I was initially there to get a referral to see a neurologist for narcolepsy. She saw on my medical history that I had a tonsillectomy and she asked if they took my adenoids or checked my thyroid. Upon her saying 'thyroid' I remembered that my grandma had this cancer. After I told her that she immediately began examining my neck. She said my thyroid was enlarged and it could have cysts on it or it may be malignant. I didn't quite absorb what she said until the next day when I told my parents over the phone and I broke down in tears. I started this search about what the symptoms are...every web site says the same things...hoarseness, neck pain, difficulty breathing & swallowing and of course an enlarged thyroid. This is great in all, but can anyone be more descriptive about the hoarseness and neck pain. Where in the neck? and is the hoarseness constant or does one have to clear their throat from time to time. Sitting alone I went over and over these...and I can clearly say that yes I have all of these symptoms. I never associated these problems to anything because I didn't know there was anything wrong. When I take vitamins, I prefer to take my children's chewable vitamins because it always felt like they were getting caught right around where my thyroid is. I have a very noticeable lump in my throat all the time...sort of like when you are holding back to cry and you get that lump in your throat except not so extreme. Basically I'm just asking people to please list what their symptoms were in detail. Thank you.
