I have been experiencing a low grade fever for the past 15 days, mostly in the evenings between 7 to 10 PM, and sometimes after 4 PM. The temperature varies between 98.5F and 99.5F. I have taken Dolo 650 twice. I sometimes feel heaviness in my eyes, but it improves after eating. I have done a Widal test and CBC, which showed only a mild increase in ESR. I am unable to understand the cause of this persistent fever. What could be the reason, and what treatment should I follow?

Fever between 98.5 to 99.5F for 15 days may suggest low grade viral, post-viral, or stress related fever. Heavy eyes and evening fatigue could be from low sugar, stress, or vitamin deficiency. Mild ESR rise shows inflammation, not a major infection. Widal test is often unreliable for typhoid screening.

My grandmother is in pain from this problem. When she went to the doctor, the doctor told her that she would need a thyroid test.

I have hypothyroidism and I am on thyroxine 100 mg. Recently I got my blood test done and TSH is very low. Kindly suggest if my medicine needs to be changed? I am attaching my report.

I am four weeks pregnant. As per my blood test report, my thyroid level is 10.58. I have also undergone a gall bladder operation four years ago. Could you guide me on whether I can have a healthy baby with this high thyroid level at the initial stage? Also, please advise whether my thyroid level could have any impact on my child as he grows up.
