I am having fever on 13 oct followed by cold, the throat pain with mouth sores, on 18 oct I have to go toilet 3 times, in these days I have night sweat also, also lost my sleep. I have 2 hiv test but all are negative. What can I do, I never had a sex in my life also never kiss any girl, only my doubt is about infection through saliva or blood, I only used syringe at doctors, I have a beard not clean shave, means no use of blade. What can I do now? Shall over masturbation may result these symptoms.
