Hi
Welcome to the MedHelp forum!
You must go for a complete fever panel. Recurrent or chronic fever is seen in tuberculosis, SLE, rheumatoid arthritis, and other auto immune disorders, UTI, drug fever, sinusitis, glandular fever, otitis media, IBS, endocarditis, parasitic infestations, fungal infections, lymphomas and other cancers etc. It can even be diabetes and hyperthyroidism. Discuss with your son’s pediatrician. Take care!
IF this was continuing for 6 months your Doctors should have played defesive medicine. I always look up my duaghters symptoms and i have requested tests to be done to rule out anything possible with my daughter.
