2-4 days per week on average, severe headaches (respond to excedrin, but not plain acetaminophen or ibuprofen), low grade fevers (99.2 - 99.8, does not lower with fever reducers), sometimes with neck pain. Temperature is highest late morning and early afternoon and usually back to normal (97.5) by evening. Occasional night sweats (always on days with fevers). Only prescription meds are birth control for cramps (started after symptoms began) and adderrall (taken for many years before symptoms started) and excedrin as needed. Started summer of 2020. Less frequent early winter but started again February 2021 and has been 2-5 days a week since then. Any ideas??
