Brief Answer:
Fever, headache and sore throat suggest either viral or strep throat

Detailed Answer:
Hello,
A fever, headache, and sore throat would suggest either a viral infection or strep throat, which is caused by a bacteria. The typical signs of strep throat include fever, no cough, white pus pockets in the back of the throat, and swollen lymph nodes. Especially if you don't have a cough, I would consider strep throat possible, which would typically be treated with antibiotics to shorten the duration of the sore throat and prevent spread. Testing can be done with a throat swab to confirm the infection.

If you do have a cough or nasal congestion or drainage, this would most likely be a viral illness, which cannot be treated with antibiotics. The recommendations would be to treat this symptomatically with Ibuprofen and other throat lozenges/sprays for the sore throat.

The lumbar pain would most likely not be related to the sore throat, unless it was a viral illness also causing body aches. If you would like to tell me more about the lumbar pain, such as how long you've had it, and any other signs associated with it (pain radiating down the legs, any leg weakness), what makes it better or worse, as well as your age, I would be glad to discuss that further with you.

I hope that helps, please let me know if you have any other questions about that, and I would be glad to discuss it with you further.
Thanks.
