Hi there ~
I understand your concerns. The discomfort in your neck around the thyroid
gland needs to be examined before concluding any diagnosis. A qualified doctor can do that examination for you and also order laboratory tests. I also believe that the concerns that you express regarding discharge is due to the nocturnal emission
which is a normal phenomenon. Unless you have reason to believe that it might be urinary tract infection
or a sexually transmitted infection, I advise you to let your doctor know so that you can get started on medications for that too. I hope this helps.
Take care and have a lovely day!
