Let me preface this by saying I do have a history of Graves disease (diagnosed 17 years ago) and have been in remission for 5 years.
I have had daily fevers ranging from 100.4-102.6 for the past 5 months. Other symptoms I've experienced are night sweats, extreme fatigue, swollen glands in my neck & groin, painful nodules behind my lower knee/thigh area, high blood pressure, tachycardia, hand tremors, & chest pain. I was told I am positive for strep (without experiencing a sore throat) in Jan, Feb, April, and May. I've been on at least 4 rounds of antibiotics during those months. Fast forward to my latest visit last week where my doctor told me she doesn't think my fever and symptoms are caused from strep at all, but that I'm a carrier. She ran new tests for lyme disease, thyroid panels, and planned to refer me to an infectious disease doctor.
I got my lab results yesterday showing all tests for Lyme were negative. She said my TSH and Free T3 are indicative of hyperthyroidism and scheduled a thyroid uptake scan for this coming Wednesday. In her note she added that she believes this could explain my "low grade fever" tachycardia, high blood pressure, and she would no longer be referring me to an id doctor!
TSH: <0.005 (0.450-4.500)
T4: 9.4 (4.5-12.0)
T3 Uptake: 33 (24-39)
Free T4: 3.1 (1.2-4.9)
Free T3: 7.7 (2.0-4.4)
I am so frustrated because in all the years I've dealt with hyperthyroidism and Graves disease, never once did I experience a fever like this and never in my life have I had one this long go unexplained. I have heard of thyroid storms causing a fever but that is certainly not what's going on here. I am at my witts end and don't know what to do. I called my endocrinologist and scheduled an appointment for this week to discuss it all with her. I hope she can get me the proper referral to help get this figured out. I wish I knew what to ask for.
I would like to add my doctor also performed the following labs:
WBC: 7.5 (4.0-11)
HGB: 15.9 (12.0-16.0)
HCT: 45.7 (36.0-46.0)
Platelets: 288 (150-450)
Sed rate: 3 (0-20)
