A few weeks ago I developed fever which lasted for over 3 weeks, it finally stopped only after a course of antibiotics (azithral 1000mg for 7 days) though the focus of any infection could not be determined. Two weeks since recovery I still feel tired all the time, get out of breath easily, feel more thirsty all the time and feel like there is water retention, and suffer from major mood swings where I get quite depressed or anxious.
