Lump near thyroid area and swollen lymph nodes

Hi all.

i have recently been for a doctors appointment regarding a lump around thyroid area. i noticed the lump maybe 6 months ago but thought it may be just part of my neck as my adams apple is quite large as it is. a couple of months ago i decided maybe it may be worth getting it checked out just to be sure. the lump is fairly small but still can be seen, it goes up and down when i swallow.

doctor said size of lump is not too alarming but noticed i have swollen lymph nodes in my neck.( I am fairly positive the lymph nodes have been like this for years.)

the doctor has got me an urgent referal with a haemotologist which has slightly confused me as i thought i would see a neck specialist for the neck lump.. i am 26 year old male and consider myself fairly healthy really. around june i also noticed i have started with a small patch of vitiligo i dont know if this could be related. i had blood tests and all came back fine.... also my breathing appears to be getting worse but cant tell if this is due to anxiety as i first noticed this while studying for exams...

has anyone else had similar symptoms or does this sound familiar? any information would be great...
