Hello Doctor. My husbands has been feeling really weak and his body temperature increases rapidly and then reduces after half hr or so. He does not have any other symptoms of fever like runny nose or watery eyes. We saw a doctor and he put him on an antibiotic for 3 days assuming that it is fever but the problem still appears. Can there be other reasons for increase in body temperature?
Hello, Fever with weakness omit not resolved by antibiotic course than you can rule out hyperthyroid by serum TSH estimation for primary work up. It's advisable to investigate with CRP estimation, Elisa test for HIV and hepatitis profile, tidal test etc. for further work up.  Hope I have answered your query. Let me know if I can assist you further.
