Your labs are fine.
Don't worry.
But we may need to talk more about what you are feeling in detail.
Also .. is there any history if allergies or recurrent nasal infection.
And any pain around eyebrows.
Chronic bacterial sinusitis can cause a low grade fever and that can explain your fatigue or weakness.
Also
thyroid status is better to check in your situation, not
calcium.
Any more questions .. just feel free
