Hello people, I ve been having problems with my health recently. I get random fevers at evening time, which started 1 month ago. Addition to this is a weak and tired feeling, combined with shivering. I ve visited a hospital for blood analysis and only white bloodcells were increased, the rest of the values were all normal. I am a 20 year old male. I have done some kissing recently, no STD s as Hepatitis B or HIV can be the cause of this. I did however kiss with one girl who has a sore lip currently, which resembles Herpes Virus a lot. I have been checked thoroughly for malaria, which has been excluded. Does anyone have an answer for the fevers during evening and the weak feeling and shivering. Ps. Fever is mild, approx 38-39 degrees C.
