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.

I recently had a thyroid test, and my report mentions thyronormalcy. I would like guidance on what this means and if any action or treatment is needed.

Answered by Apollo Doctors

I have attached my recent thyroid blood test report. I am currently taking Thyronorm 100 mcg daily. Based on my report, could you please advise if my dosage should be adjusted?
