Hi,
Welcome to HCM,
In normal condition if adequate amount of thyroid hormone are produced the TSH is suppressed by feed back,but if Thyroid gland is under active due to any reason then more TSH is released and it level rising is very good test to diagnose Hypothyroidism,once this is supplemented in the form of tablet Eltroxin this TSH value will become normal .
Hypothyroid is common ly due to autoimmune process, but it can be due ti other causes as well like surgery,malignancy.
TLC is high indicate infection and use of antibiotic depend on site of infection and organism involved if it is not working please visit Physician again to asses the condition and if any further testing is required or suitable antibiotic may be required.
Take care
Good Luck.

I am concerned about my husband s condition. About 2 weeks ago he started with shaking chills and severe headache, mostly the left side of his head and developed a fever of 102, no other symptoms. Fever lasted about 3 days, lower during the day, up at night. On the fourth day he developed a mild, dry cough. Was put on Zithromax 5 days treatment, felt better for about 2 days, fever broke still had some spikes of 99.8-100 during the night. Started to sweat profusely. A week later, noticed 2 small lumps, bean shaped and hard to the left side of neck.(mentioned some tenderness when pressing on them but not much) On day 9-th saw another Doctor who diagnosed his condition as pharyngitis and prescribed Pennicillin V 250 mg q 6h for 10 days.Had lab work done CBC, chem panel and TSH, all came back normal. Also chest x-ray done, results normal. He is not feeling better, does not have the high fever anymore but spikes low grade of 99- 99.2 starting in the evening.Continues to have drenching sweats, has to change bedding 2-3 times/night., started to c/o of pain in lower extremities, bone and muscle. Appetite is OK, has energy during the day, evenings starts to feel sick. Could this be something viral? Is it possible to have bacterial infection without elevated WBC S? Lab work was done after he was treated with antibiotics for quite a few days. I am worried since I did a lot of reading about lymphoma, night sweats and swollen nodules.

I had low grade fever yesterday 98.x to 99; the doctor said I have wheezing and it is bronchitis. He subscribed 5-day antibiotics for me. Today is my 2nd day, but my fever seems went up to high 99.6 to 99.8. Should I be concerned? Would this be an indication that the antibiotics doesn t work?

doctor1 MD

I have been running a low grade fever of between 99 and 100 degrees every morning for roughly a little over 2 weeks. It would come and go throughout the first few days, but now it seems to dissipate after I am work for a about an hour. I feel mostly fine aside from that. I think my other symptoms are related to a completely different problem

Hey, Im a 25 year old male. I have been having symptoms of hypothyroidism and a few of hyperthyroidism, such as cold hands and feet, sensitivity to cold, dry skin, I never sweat even when exercising, low heart rate ( 52 BPM resting) but also have social anxiety and nervousness. I recently had a blood test done at a near by lab for cheap. TSH     1.580 Thyroxine (T4)     8.2 ug/dL T3 Uptake     35% Free Thyroxine Index     2.9 Do you see any problems there? I can t go to a doctor because i have no health insurance and have no money. I also read that hypothyroidism can play a part in delayed puberty. I didn t see any development until i was 16/17 and still look very young and feel underdeveloped. Is there anything else that could cause these symptoms? Should I get more blood work done?

Hi, I am having all the symptoms of underactive thyroid but my blood results have been returned 3 times as OK. However, visiting doctor again he examined my neck and told me I had a goiter and would take more bloods, I am feeling really ill and should also mention that I have Rheumatoid Arthritis and see a Rheumatologist twice a year. Could this result in my having an operation and after start to feel better and loose weight? Thank You
