Six days ago I felt very tired and physically weak so I went home from work earlier. Took my temperature and the thermometer showed 39.3°C (103°F). Swallowed two Tylenols (actually, it was not Tylenol, but the European version of it) and went to sleep. My body temperature dropped but I kept feeling severe fatigue. Well, the next morning was better, but the temperare was still dangerously close to 38°C. I noticed my mouth feels very dry despite drinking a lot of unsweetened beverages (no caffeine). Because no other symptoms occured, I went to work and kept using "Tylenol". Now, after a few days, my temperature is still slightly elevated (37.2-6°C), I still feel kind of tired and today, my nose bled for about 30 sec. for no reason whatsoever. Also, as I am a very active sportsman, I noticed an increase in my resting heart rate - from 45-48 (depending on how much I train) to 60 (give or take).
Does anyone have an idea what this might be? Thank you!
