What Causes Fever While On Advil?
you should be examined by a doctor
Detailed Answer:
Hello,
If you don't have any other symptoms (like cough, headache, sore throat, flank pain, urinary tract symptoms, etc) then the most likely cause is a viral infection. Despite that, a fever as high as yours may be associated with serious infections sometimes. So a visit to your doctor sounds appropriate. Pyelonephritis, meningitis, pneumonia and other infections may be causing it. Your doctor can elicit signs of various infections during clinical examination. If necessary some further tests may be ordered. For example a urinary tract infection requires a urinalysis for confirmation.
I can't comment on the ticks but Lyme disease usually presents with a characteristic skin lesion; a circular redness that transforms into a red circle with gradually increasing radius and normal skin in the center.
If you've been bitten by a tick then tick-borne diseases can be considered. If you haven't found any ticks on your skin then a bite does not sound likely.
