My husband,
for a year kept saying to primary care docs that he was exhausted all the time( naturally they told him he was depressed, and of course threw a prescription at him) and oh, those little pea sides nodules that they could feel in his neck was just a swollen lymphnode, he probably was fighting off a virus of some sort.
Guess What after enough pushing and one year later he was diagnosed with stage 3B Nodular Sclerosing Hodgkins Lymphoma and Papillary Thyroid Carcinoma.
MY STRONG ADVISE TO YOU IS BE YOUR OWN ADVOCATE DEMAND TESTING AND IF THEY WILL NOT LISTEN TO YOU FIND A DOCTOR WHO WILL.
Good Luck, and God Speed
