Thank you very much for the detailed answer.
Hi
Welcome to the MedHelp forum!
Recurrent or chronic fever is seen in typhoid, tuberculosis, hepatitis, SLE, rheumatoid arthritis, Polyarteritis nodosa (PAN) and other auto immune disorders, UTI, drug fever, sinusitis, glandular fever, otitis media, IBS, HIV, STDs, endocarditis, parasitic infestations (like malaria), fungal infections, lymphomas and other cancers etc. It can even be diabetes and hyperthyroidism.
Since I cannot examine you and know other related conditions you may be having, nor is a detailed history possible on net, I have listed the various possibilities that should be looked into. Some have been tested, for others please consult your PCP.
Take care!
