I have realised that I never get a fever anymore, even when faced with serious bacterial infections, that normally would give a fever. If I remember correctly, I haven't gotten a fever in 10 years, since the initial onset of my symptoms. Before that, I had at least 1 fever a year. Fever isn't a bad thing per se, as it can kill off certain pathogens. Most doctors would rather have patients do without fevers though. Do you still get fevers?
