What Causes Persistent Low Grade Fever And Joint Pain With A History Of Bacterial Infection?

my 15 year old son had a stomach virus 2 weeks ago and has joint tenderness with swelling of which resulted in 2 ER visits. Diagnosis: viral attach of the left ankle joint with cellulitis setting in. 3 different blood test profiles showed NOTHING. 2different ankle fluid taps did not show a bacterial infection so their original diagnosis of viral attach still stands. He has a chronic low grade temp of 99.4 each night at this time. What are they missing? Arthritis profiles were negative. He is taking voltaren bidand Cephlexin 300 mg 4X and continues to take some Tylenol as needed for pain in the bottom of his feet

Hi,

I had gone through your question and understand your concerns.
It can be reactive arthritis secondary to infection that your baby had. As his arthritis profile is negative and his fluid aspirate is negative for bacteria. Your treating physician should rule out tuberculosis of joints. Continue NSAIDs group of medicine as prescribed by your physician. Likely its reactive arthritis that usually settles after 02 months but in some patients it can persist for 06 months.

Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions.
