--Help--anyone--Scaredy Cat, Jen, ---I'm confused!!! As you know--me & wife just returned from midwest -to home in East Coast. For background info---i suffer from---Mitral Valve prolapse-SVT-irritable bowel syndrome- anxiety----& chronic fatigue.
Anyway---my cardio wanted me to see an endocrinolgist--'cause in May---he took a blood test for TSH (Thyroid)---he was looking for "hyperactive" thyroid---well...my TSH came back slightly above normal (5.4)--indicating a possoble "Underactive" thyroid (Hypothyroid)---
So---while in midwest--set up an endo appt. (Here in Philly --i had to wait till September!!! Can you believe that???)
Very good Dr. --Did thorough exam--felt thyroid---asked questions----I received TWO ultrasounds---one in his office & a more specific one in another room---AND---blood test (For TSH..& free T-4s)----Bottom line is EVERYTHING came back normal----!!!!! In fact my TSH was 2.7 (HALF of what it was in Dr. office in Philly 2 months eralier.)---My blood test for free T-4 normal....ultrasound normal---& blood test for Hashimotos disease--negative--normal. ------Dr. Nurse---a WONDERFUL midwestern lady called me at my hotel--giving me "good news"---
Now--back in Philly---today--get copy of med report sent to my cardiologist & family Dr. ----Says everything i mentioned----no underactive thyroid...---Probably..."Euthyroid Sick Syndrome"!!!! I checked it out on internet---seems to mean--thyroid normal--but...abnormal reading could be due to body's reaction to another illnesss or stress (hello?)---
My wife said--the endocrinologist did not seemed concerned--nor did his nurse when she gave me results (just follow up TSH in one year)_---Has ANYONE here heard of "Euthyroid Sick Syndrome"...or have it??????? 
I'm driving myself batty ---again---looking on internet---wife said probably just stress----hope i do not have an "underlying" disease. Please---someone----get back---I'm calling the nice endo nurse Monday morning...in meantime----What the heck is this??? Thanks--Robert
