I have a similar problem with low grade fever, which used to occur for 6 years in spring and summer-time, but now I have it constantly for the last two years. Quite detailed blood tests seem fine apart from elevated IgE (1000), no visible signs of allergy, but I developed lately post nasal drip. Anyone heard what may cause such symptoms and how to cure them? Thank you!
after thought, Lupus is something that has alot of the symptoms u mentioned. good luck. finding the diagnosis can be the worst part
Could be allergies. get tested for seasonal and food allergies. All those symptoms are allergy symptoms best of luck
